Re: My blower fan only runs on high
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 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.------------------------------------------------------------------------------------ Launch CResetter Oil Lamp Reset Tool
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.
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
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.
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.
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....firstname.lastname@example.org
