2005 E150 Fored Van Rear Fan Only Works on High

It is a common concern of Edsel Bryant Ford crown victoria owners to state something to the issue of "my blower motor only works good happening the high speed". In which case, the blower motor might non spin on whatever speed opposite than high. Or the blower motor might whirl on speeds otherwise superior, just turn sort o slowly and move tokenish amounts of air. The most likely culprits here are the blower resistor low the hood and it's associated electrical wiring pigtail.

Hera's the inside of our project elevator car, a 1997 crown victoria police interceptor p71.

And here are the manual clime controls.

We also have an aftermarket radio installed too. That big black button in between the climate controls and the radio is to pop the trunk open. Noncombatant vehicles would have a clock there instead of a button.

Present's the wiring pigtail kit that is going to be installed.

And a closeup of the part turn tag.

And the instruction manual of arms that ford includes with the wiring pigtail kits

Here are a couple closeup pictures of the new blower resistor pigtail

The blower resistor wiring pigtail is likewise avaliable aftermarket from NAPA with color coded wires. But the napa blower resistor pigtail does non include the electrify crimps OR adhesive heatshrink tubing like the resistor pigtail outfit that you can purchase at your local ford dealership.

And here is the blower resistance pigtail after being removed from the cetacean resistor.

Here's the harness with the resistor pigtail cut off.

And after the wiring insulant has been stripped off the ends, the heatshrink tubing slid on, and the crimp connectors crimped on.

Remember to sloping trough the heatshrink tubing on the wiring in front crimping the connections together.

Also, make a point to stagger the splices at different locations so that you don't finish with a really huge diameter glob of plication connectors next to each other.

And afterwards heating a the heatshrink tubing to shrink it down in sizing.

Now the wiring is ordered backbone inside the black looming and wrapped with some electrical tape.

And now the wiring is placed back in the proper position to tie to the blower resistor and then slid onto the resistor connection.

And a few Thomas More pictures from various angles around a 1997 police police cruiser locomotive bay.

The new pigtail install looks quite professional. Most people would not cost able to state that a new wiring pigtail had been spliced on at a quick coup d'oeil.

And here's where the electric fan resistor is located.

Banknote that this particular car is a 2000 crown victoria police interceptor. And that various parts take in been removed including:
-Heater center hoses
-Windshield wiper hood
-Engine fabrication
-Transmission assembly

And here's a 1998 summit victoria police interceptor with the blower resistor removed.

With the engine installed, mention how incomprehensive headway is between the spinal column of the valve cover and the a/c evaporator housing.

And the electric fan resistor itself.

The wire wound coils are constructed of nichrome wire care you'd find in your kitchen toaster

Here you can pick up the thermal blend which blows if the temperature gets above 250°F. Once information technology's winded, it does not readjust and the resistor fabrication must be replaced.

A couple of the connector pins were somewhat rusty on this particular resistor.

And a plot of the components inside the cetacean mammal motor resistor assembly

Here are a few pictures of a burned resistor wiring pigtail from a 1998 police interceptor. The blower motor did spin on speeds some other than mellow, but spun rather tardily.

While you are replacing the blower resistor, it would be a good idea clean debris that may have lodged along the evaporator core. You can do this aside removing the blower motor and reaching in with your hands to pull off any remaining debris, then laundry off the remainder using a garden hose. Your new blower motor resistance will have a preferably short life if an inadequate amount of zephyr is flowing by to cool it.

To absent the blower motor, remove the 4 retaining fasteners and pull forwards

Now that the blower motor is out, you can pass wrong to the right and get the debris off of the evaporator core.

You Don't get to tear the whole evaporator housing out of the railcar like this. But it's difficult to get good pictures deep down the evaporator housing with the housing still installed on the car. If you would like to view some extra pictures of the evaporator trapping, suction stop here.

The evaporator Acts like an air filter. In this case it caught pine needles and various plant pollens from the unlikely air. And when connected max a/c IT had recirculated from the interior passenger compartment flowing through it and caught linen debris from the passenger's vesture. Passengers have been prohibited from smoking cigarettes inner this vehicle, thus there aren't any tar deposits on the evaporator core.

These cars do not have a seperate cabin air cleaner to contend with like in other fords.

And here are a few pictures of a 1994 poll victoria with the dashboard removed. The physical object here is to illustrate where the blower motor resistance is in relation to the interior of the car.

Blower resistors for 2005-2010 crownvics

Here are a some pictures of the blower resistor used in the middle-2005 and later crownvics with manual climate controls. There are no obvious problems with this resistance or wiring pigtail, but the donor car no longer needs these parts any longer since it was wrecked and is being "parted come out" aside a salvage grounds.

Blower resistors for 1980's "corner body" crown vics.

GM_Guy on www.crownvic.net had to supplant a cetacean mammal the cetacean motor resistor in his 1989 grand marquis and made the following observations:

• 1983-1989 crownvics without the self-acting temperature ascendance arrangement use the same E3AZ-19A706-A blower resistance as later 1990-2005 vehicles despite what your local anesthetic ford dealer's parts catalog system will take.
• 1980's crownvics with automatic temperature control use a unique blower resistance, ford division #E4VY-19A706-A and pe-tsai part #ECH-BR311. Below are a couple pictures of this resistor assembly.

And here is the ECH-EC75 wiring pigtail associated with the ECH-BR311 blower resistor for 1980's crownvics with automatic temperature keep in line.

Notes:

• The burned resistor connector is from a 1998 pate victoria that came from a southern state where chloride rock salts are not used on the roads during the winter. And yes, "rust free" cars in southern states do indeed get corroding on this character.
• A large portion of crown victoria owners with failed blower resistance parts appear to just complain that their blower motor doesn't work well for years on end, and never bother to actually fix the problem.
• A new electric fan resistance and pigtail will cost about $50 at your local ford dealer.
• Attempting to situate a "pre-owned" resistor and pigtail from a wrecked salvage yard crown vic is likely to be unproductive as salvage yards often aren't heedful with wiring and break the resistor and IT's pigtail into little broken peices when removing a car's locomotive. Besides, galore of the crown vics that you'll find wish have a resistor pigtail in as mischievous or worse check than your's presently is. And in that location is also a tendency among wrecking yards to become "full service" and not get you access the cars in the grand like the old "self-service" yards used to.
• Another problem that sometimes afflicts patrol cruisers is that all air flows out the deicer vents rather than the dashboard vents or coldcock vents. This is caused by a vacuum leak somewhere. But the focussing of this article is on the electrical control aspects of the blower centrifugal rather than the emptiness controlled mode room access actuators inside the heater plenum box.
• The blower resistance is cooled away air flowing by it. An used wornout blower causative that consumes too much powerfulness and moves too little air will causa premature failure of the resistance.
• The cetacean mammal motor electrical connector was revised part way into the 2004 model class. Service part literature lists the transistion date from the old style physical phenomenon connector to the new style electrical connection Eastern Samoa 04/20/04. Crownvics manufactured before 4/19/04 got the old style blower motorial connecter. Crownvics manufactured from 04/20/04 got the red-hot style electric fan motor physical phenomenon connective.
  
• Part way into the 2005 model year, the blower resistor, the blower resistor pigtail and the associated hole in the evaporator housing were altered. The new blower resistor setup is not compatible with evaporator housings designed for the longtime blower resistor setup or vise-versa. Ford service parts literature lists the transistion date back the old style blower resistor and electric connector to the sunrise style apparatus arsenic 12/06/05.
  
• Sometimes, the blower speed hold in switch privileged the auto and it's associated electrical connection are trodden due to excessive hotness. However, it is a lot more common to have a damaged blower resistance/pigtail in the engine bay than a tumble-down blower motor operate switch/pigtail in the passenger cabin.
• Much of the Homemade (DIY) car repair crowd seem unaware that their cable car justified has a blower resistor in it. This often leads to the shadetree mechanical replacing the blower speed contain switch on the dashboard inside their car, only to be puzzled wherefore their blower motor still only spins on the "high speed".
• The subroutine for replacing a damaged cetacean motor speed control in a crown vic with EATC operating theater ATC is similar to the process for replacing a impaired cetacean mammal resistor in a car with manual climate controls. However, the part numbers enrolled above are not applicable to cars with EATC or ATC climate ascertain systems. Some pictures of the the 1998-2010 eatc cetacean mammal quicken controller are avaliable by clicking here. And some pictures of the unique blower resistance used in the 1990-1991 crownvics with ATC are avaliable by clicking here.
• A copy of the ford motorcraft wiring pigtail catalog is avaliable by clicking here. This catalog lists many other wiring connectors that are utilised in your crownvic much as a blower motor connector, a blend room access actuator connector, an air conditioner compressor clasp connector, etc.
• You need a 1/4" rachet up, or s extension bars, a swivel, some flexable physical phenomenon tape to wrap around the pivot and mayhap a flex shaft to access the bolts which hold the blower resistor to the evaporator housing happening your 4.6L crownvic. About automatically minded citizenry should be able to figure out some kind of frame-up that will work for this project. The big stumbling point for most shadetree mechanics is calculation out that the blower resistor is the cause of their problems so obtaining the necessary theatrical role numbers to order the refreshing blower resistance and wiring pigtail.
• Autozone and to the highest degree unusual aftermarket parts retailers answer not sell cetacean mammal resistance wiring pigtails for the crownvic. They will however sell you a blower resistor. But installing a newly blower resistor will manage you little good if your resistor wiring pigtail is badly busted.
• Your localised ford franchise and the your section aftermarket NAPA parts retailer do sell cetacean resistor repair pigtails, but you might have to manually ply your parts consultant with the part phone number listed above to actually order ane. Just vocation up the parts store and saying "i need a blower resistor repair pigtail for a 1997 summit victoria" sometimes results in the parts consultant locution "nope. put on't have one." because the blower resistor pigtail is catalogued in a hidden section of the catalog that they missed.
  
• The blower resistor is a part specific to the crown victoria and grand Donald Robert Perry Marqui. Merely the electrical connector pigtail for the cetacean resistor is divided up with numerous other elderly ford vehicles.

Notes:

• whatever Edsel Bryant Ford vehicles the likes of the taurus have the blower resistor located at bottom the car which lowers the chance of finding a "invalid" wiring pigtail that's really corroded.
• some ford vehicles like the crownvic and taurus could be logical with two different climate control system options. and eatc vehicles use a different blower resistor connexion than vehicles without eatc.
• roughly large ford trucks suchlike the excursion have two blower resistors in the vehicle for the two hvac blower motors (front & rear).
• the infomedia microcat and proquest cpd service part armoury computer software that your local ford franchise uses has very limited information avaliable about service parts for 1980's ford vehicles. support for the pre-1990 ford vehicles has largely been eliminated. this is wherefore aftermarket application info is listed above.
• in service parts literature, there is citation that some of the F600/F700/F800/F650/F750 fleshy Gerald R. Ford trucks apply a crownvic blower resistor connector overly.
• If you are looking tall-to-find electrical connectors for older legacy applications, you might visit the Railway car-Pak Manufacturing website. Not only does this company manufacture the 91-6881 blower resistor connector for senior ford vehicles, but they also manufacture new hard-to-find physical phenomenon connector pigtails for older chrysler and general motors vehicles also. Do note that railroad car-pak manufacturing does not betray in real time to the public, and you take to buy through an authorized distributor.

Cetacean mammal motor replacing notes:

The hole turn over the evaporator box to mount the blower motor hasn't changed since the early 1980's crownvics. However the blower motorial electrical connector has been amended a few times concluded the old age.

• Currently, ford dealerships only deal out blower motors that use the rising title physical phenomenon connector first introduced in the late 2004 model year starting connected 4/20/04. The current part # for the crownvic blower motor is 4W7Z-19805-AA (MM929)
• In that location is a plug in pinny tackle avaliable for installing a later model cetacean mammal motive into an sooner 1992-2004 car, part #4W7Z-14A411-B (WT-56853). You could also cut off your old wiring pigtail and splice on a new one using kit 3U2Z-14S411-YBA (WPT-605) instead.
  
• To confuse matters even further, there is yet some other different cetacean mammal motor electrical connector used on the 1991 & earlier box body crownvics overly. The parting # for the adapter harness to use a 1992+ blower motor in one of these legacy vehicles was F1AZ-18C629-A but this harness has since been discontinued and is no longer avaliable.
• If you need a blower centrifugal electrical connective for your 1992-2004 crownvic that still has information technology's original blower motor installed, the part # for the wiring pigtail is: 1U2Z-14S411-CA (WPT-104)
• Thither are aftermarket blower motors avaliable for the 1992-2004 crownvics that have the innovative style electrical connective on them. Instalmen one of these blower motors into your 92-04 crownvic would embody easier than splicing on the later style wiring pigtail, and less high-ticket than buying the adapter to exercise the later style blower motive in your car.
  
• In that location are also aftermarket blower motors that father't have an electrical connector at complete. Or else, they have two wires hanging out of the motor that you need to splice onto your car's electrical harness. When splicing one of these motors into your car, you need to pay attending to polarity. If you relate the wires backwards, the motor will spin backwards and move a selfsame minimal number of air.
  

If your blower motor doesn't spin in the least, hither are a duad troubleshooting tips:

• Much of the Come-It-Yourself (DIY) railway car repair crowd appear unfamilar with the concept that the blower motor is controlled by a resistor inline with the background side of the motor. Just because the blower motive electrical connexion has +12V present on one pin does non necessarily mean that the blower motor will spin after you set u the connector. You as wel ask a ground way on the other terminal of the blower motorial connecter to get the motor spinning.
• If you're wondering whether your blower drive is non spinning at all because of an issue with the resistor, wiring, OR the motor itself, a good terminus a quo is to remove the electrical connective from the blower motor and run deuce high guage wires directly to the vehicles battery to for temporary testing purposes. Be careful with this method acting, the blower motor draws stacks of electric power and could movement thin wires to get sort o hot. You'll also generate extraordinary sparks when you touch the wires to the electric battery terminals and motor contacts.
  

In the 1992-1997 crownvics, the factory workshop manual says to remove the railway locomotive coolant reservoir to obtain sufficent space to be healthy to slide down the blower motorial out. Unfortunetly, the nuts are usually rust-fastened to the mounting studs which hold the reservoir to the wing apron. This means, you can't remove the coolant reservoir without destroying it. Even so, on that point is an alternate solution that is not certificated in the mill betray manual:

• jack upwardly the front man of the car
• remove the front passenger's tire
• remove the two thru bolts that delay the fender apron to the pilot
• tease the fender apron framework angle bracket
• pull the back of the fender apron back some near the blower motor box seat
• click here to view to pictures of a crownvic with the buffer apron out entirely to give you an idea of how the fender apron is held in. (you don't need to pull yours retired alike this, just move it around a little bit)

In the aftermarket, it is ordinary to require you to reprocess your onetime blower wheel on your new blower motor. However, you'll often end up destroying your age-old blower squirrel cage attempting to get it off the blower motor spear. So you will probably need to order a new blower motor wheel before you come out installing your new blower motor.

In the aftermarket, there are also some rattling noisy blower motors avaliable. If you source from the aftermarket, you might privation to superpowe up the new motor in front you effort to dispatch your mature one. If your new centrifugal seems too noisy, chatter another parts store and mystify a different ane from a different manufacturer. If your blower motor already has the blower wheel installed on information technology, be aware that these are high torque motors and the blower causative will neediness to motion around a bunch when you apply power to that.

A bad blower motor will often take prohibited the blower resistor when it fails. The blower resistance is normally cooled away the air flowing across it from the blower motor spinning. An old wornout blower motorial that refuses to spin around will draw heavy amounts of power and can overheat a blower resistor very quickly. You leave wear the bearings and brushes in your new cetacean motor at an accelerated value if your blower resistor is damaged so that you're forced to run the blower motor on the "high speed" scope whenever you want heated up or air conditioned air.

Having a non-functional electric fan motor is a safety issue. It's selfsame unsafe to drive during the gelid winter months when your windshield is covered in methamphetamine surgery pull the wool over someone's eyes because you can't heat the chalk to melt information technology off. It's likewise dangerous to drive during the wet summertime months to drive with foggy windows. And in several parts of the suprasegmental states, you could end sprouted with heatstroke from not having a functional ventilate conditioning organisation during the hot summer months. None the less, roughly penny pinching cable car owners drive around for extended periods of time without functional blower motors.

Dubiousness & Resolution

Is all the above information really needful?

This clause was composed with the diy shadetree machinist in mind and contains lots of screen backgroun information. If you'Re a professional person mechanic, all you will probably need to know are the separate numbers for the cetacean resistance & blower resistance pigtail.

How hard is it to replace the blower motor in a pate victoria?

This is very easy task in the 1998 and later crownvics if you get a motor that already has the blower rack installed. Just remove an electric connector, remove four bolts, slide the old blower drive out, and reassemble everything with your new blower motor. Do personify warned that replacing the electric fan motor is a more involved task on the 1992-1997 cars, because you'll need to drop the fender apron down some like mentioned above.

How hard is it to replace the cetacean mammal motor resistor in a crown victoria?

This is a difficult task in the 1992-2010 crownvics. These cars utilise the 4.6L engine that has a tall locomotive engine valve cover placed in front line of the cetacean resistor along with some heater nitty-gritty hoses routed near the resistor likewise. You will need a 1/4" ratchet, several wing parallel bars, some pivot adapters on with lots of forbearance for this task.

Should I have my local ford dealership put in a original blower resistor & pigtail for me?

If you do not like frustrating hands-on car projects, this would cost a real simple answer. Just describe your problems to the dealership service advisor, hand them your machine keys, and pickax up your auto when it's primed a while later. Do equal warned that your notecase will become a few hundred dollars flatboat if you choose this option though.

Should I acquire a replacement blower motor from the local salvage yard?

This can be a good option for some people. Your local salvage yard probably has a bunch of good employed blower motors on hand ready for present delivery. Do comprise warned that some electric fan motors wish birth a tobacco odor to them if the previous owner of the wrecked car was a cigarette smoker though.

Should I acquire a replacement blower motor resistor from the local salvage curtilage?

No. Just about of the crownvic blower resistors and cetacean mammal resistor pigtails at your local salvage yard are likely to cost in look-alike condition to your broken ones. Also, most full religious service salvage yards don't sell cheap small parts like blower resistors separately.
