Hi there!

Yes it sounds like it, or may have corrosion on the contacts.

It's usually located in the airflow section near the blower motor. Look for wires from the motor going directly into the plastic ducting. The resistor should be on the other side. Usually has screws or a plug to remove it.

Look under the plastic at the end of winsheild.
Remove the 8 clips.
Under drivers wiper arm you'll see the blower with 2 straps.
Un-hook them and remove plastic cover.
Under the blower motor are the resistor coils.
Hold of plastic on top with a pair of pliers and pullout the whole thing.

Search Ebay for a replacement, as there are several sellers offering them much cheaper than the main dealers - unless you want to go down that route.

If this solves your problem, Please take a moment to rate as Fixya! Thank you.

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.

I have a 98 durango the fan only works on the 3 low speeds not the highest speed. It's like that for a/c and heating.


.it could be the resister block for the fan only on the high speed resister side.you would have to remove the resister to inspect it for damage(broken resister wire)this would be the thickest wire on the resister block.it is located in the air box near the blower motor,as it needs the air flow to keep itself cool enough.there is a wire plug that has about 4-5 wires on it.also it could be the fan control switch on the dash that you turn to get the different fan speeds.

The blower resister located near the blower motor is bad,this is what controls the speeds,except the high setting.

The fan/blower only works on the high setting.


It probably is the fan switch itself. They are around $30. for a new one. You can take it out and check to see if you have power to all the settings with a ohm meter or test light. They are not real hard to take out.

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.
