It's (blower motor resistor) mounted to the bottom of the heater box with 2 screws in back of and below the glove box. remove the passenger hush panel under the dash and it's right there next to the motor.
PLEASE RATE THIS FIX, THANKS

    If u really twist around under the dash no, but to make it easy remove the glove box liner, it only takes a few min's

Fan control switch only works on high


If you blower fan will only work on high know that most blower motors are power by a basic electrical circuit that utilizes a multi resistor or a solid-state resistor to control different fan speed modes (low, medium low, medium and high). If the resistor malfunctions it may lose one or more of the lower fan speed settings. First check the fuse and change if needed. If that doesn't fix things change the resister.------------------------------------------------------------------------------------

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.

The fan in my 2002 GMC Savana cargo van doesn't work. I lost low, then medium speed, and finally the high speed.I checked the fuses and relays.I changed the blower resister, still no fan. The heat


Hi Jim, If the vehicle is fitted with climate control it will have electronic management. However it can be wired by someone knowing electrical circuitry to by pass the control. It will save you some cash but will need manual control. Make sure whoever does the job knows what he or she is doing. Have a happy new year. Regards John

I have a 1999 Jeep Wrangler and the heater fan stopped working for all the fan speeds. The fuses are fine. How do you know if it is the blower resistor or the blower motor?


If you bypass the resistor pack and connect the motor directly to the fused 12v supply then the fan should run at maximum speed. If so, it's the resistor pack that's blown: a very common fault on a huge number of makes and models.

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.

The fan speed control does not slow the blower down past about 75 percent of full speed.. It's like it only has the upper 25 percent of fan speed range now. No change going from auto to manual.. I can...


My name is Ron,and I will try to assist you.There is a blower motor resister that controls the speed that you set on the speed control,manual,or automatic.It is located near the blower motor.Most of the time under the dash,behind the glove box.It most likely mounted with two,maybe three screws.If it is not in that location,look under the hood passengers side,under the windshield, on the fire wall.It will have a multi-wire plug in going to it.Take the screws out,not loosing them(they are small)and pull the resister out toward you.When reinstalling the resister,be carefull not to bend it up.If I can be of more help,please let me know....roniecon@gmail.com

check blower motor resister in plenum housing if this is manual system.
If electronic, check blower motor speed controller.
