Question about 1993 Chevrolet K1500

1 Answer

He heater/AC control unit on my 1993 chevy truck just stopped working (the lights won't come on). I went to a salvage yard and got a replacement, hooked it up and it still didn't work. I had checked the fuse and it was fine. When I turned the ignition switch and pulled out the fuse there was no spark when I plugged it back in. Is there a additional fuse that I don't know about?

There is only one fuse. If you are not getting power on the brown wire, are you getting power at the fuse? If yes, trace the brown wire back to the fuse.

Repair temp control

First. Check all the fuses-focus on the blower motor fuse. The fuse box is located near the hood release lever.
Make sure the slide levers controlling air direction and heat are at the top position. Make sure that the blower switch is on high.
Carefully pull temp control unit out about 2 inches, by removing 2 screws at bottom of unit. Get a test light, and check for current to the unit and blower motor.Make sure the connections to the switches are good.
Check the resistor connection to the blower motor. It is in the engine compartment on the AC condenser housing- at the firewall.
Check all the connections related to the blower motor and make sure there is current to the unit.
A test light will help determine what is at fault. If it is a switch behind the control unit, replace the whole unit. Your local auto salvage yard could have one.
Good luck.

The fan speed switch for the heater/ac will not work on the two lowest speeds, only med to high. Went to a salvage yard and got a replacement one, it does the same thing. Apparently there is something...

You need to get the blower motor resistor replaced.This is your problem.It is located by the blower motor.There will be a connector from the blower to the resistor.The resistor controls the fan speeds when you turn the knob on the control head.The blower motor is on the passengers side under the dash.Hope this helps.Good luck.

The knob on the heater control is loose and I can't adjust the temperature. Will replacing the knob work or do I have to bring the car to the service department for it to be fixed?

You can try a Salvage yard or just order the knob at a Dealer. I went through the same thing with my 1999. If you look behind the knob you will probably see a crack where the metal clip sits.

My Salvage yards do not want to sell the Knob separate from the whole control unit. Yours may. It will be available at a Dealer and with Patience you can replace it yourself. You will see an irregular clear plastic shape behind the knob and that is all that needs lining up.

I would suggest changing the control head. You should be able to source a used unit from a local salvage yard.
