fords are notorius for faulty fan switches, you will need to get a new one, but it will probably fail in a year or two.

SOURCE: blower fan

Sounds like the problem is more with the blower motor assembly itself. The blower motor have micro-proccers built itnto them which comunicate with the control heads and do the actual regulating of the fan motor. Dealers have computers with diagnostic software which allows them to monitor what is happening in the eletronic controls of the vehicle. Electronic diagnostics without the diagnostic software makes it very diffecult to pinpoint the actual item causing the problem.

SOURCE: Blower motor on 96 Isuzu Rodeo does not blow on

if fuses are good, check for power at blower motor, when truck is running and a/c on. the resistor and the switch provide ground, so the blue/white wire should have power, and the blue/black wire should have NO power, if it does have power, then most likely the resistor is bad. if it has no power and the motor doesnt run, the motor is bad.

1992 chevy C1500: Heat works on low speed, no medium, and high only works intermittantly.


On any other vehicle it sounds like the blower fan switch.
The fan switch provides power or ground to the resistor and there would be a high speed blower relay to bypass the resistor.
But in your case the fan switch is part of the controller.
I don't have a diagram for a 92 but the 94 model shows relays for low medium and high speeds. Each relay gets power from a fuseable link. The high relay gets power thru the low relay if the low relay is not engaged.
If you have the model with 3 relays you may need to check them.

There is a blower motor resister that has gone bad,also check the blower switch on the back,the connection could be burned ,the blower motor causes this to happen,even though it sounds ok,it is drawing to many amps.

2000 Ford Taurus - A/C fan only works on high; cool air is "available" but not blown as fan won't run, except in "high" position. Any suggestions?


The low speeds(all of them) are distributed threw the fan speed switch to the blower motor resister.The resister is the problem.It is located very near the blower motor.It has two screws mounting it to the blower box.It has a plug in with about 5 to 7 wires.Unplug this plug to the resister.Remove the screws.Pull the resister toward you,it mounts and rest inside of the blower case,this is how it is cooled.Now when you replace the resister,replace the blower motor.Even if the bower motor is running fine, it is pulling to many amps for the resister.It will happen again soon,if you don`t replace the blower motor.If I can help you any more,please let me know.

Heater Control Switch Only Works on High


Your problem is probably a part called the heater resistor block or board. When this part burns out you will only have high speed on the fan. On my 1999 voyager it is located on the firewall and it snaps in a hole in the firewall. This is under the hood behind the alternator.
Mine had a multi pin black plug plugged into it. Unplug the plug and
you should be able to pull the block out insert new block and plug plug back in and it should come to life.
