Question about 2002 Chevrolet S-10
My fan has intermittently worked since I bought the truck a year ago. It has finally quit working in any of the settings. Is there a relay or some other control device I can replace to make it work?
BASE HVAC HAS BLOWER RELAY FOR HI ONLY
AND A RESISTOR FOR ALL OTHER SPEEDS
AUTO HVAC HAS BLOWER MODULE FOR CONTROL
CHECK ALL CONNECTIONS FOR CORRODED OR BURNT
TERMINALS. TEST POWER AND GROUNDS

I suspect you also checked the fuses, some vehicles are double protected, especially since you usually have to remove the entire dash panel to get to the heater fan blower motor. It should be in the middle or under the glove box, should be located in a plastic box that has like a bell shape to where the motor is. check fuses then check wiring, and make absolutely certain the relay was the correct one that you changed, in a 3 year old vehicle the fan motor should not be bad yet.

First off CK your curise control throttle cable. You should start at the throttle body where the two cables connect to it. (throttle and cruise control cables) This is where I have found is the most common problem is located. Make sure the curise cable is connected and not broken or cut. I have found this to be a very common problem.
If you find them intact. Then its too easy from there. Just trace the cable back to the electric motor that works the cable and so forth. From my experiance your problem is mechanical not electrical.

There is a resistor panel that controls the fan speeds behind the glove box on the dash. You remove the glove box and you will see the airbox. Sitting down in the left top, with 2 screws holding it in, will be the resistor panel. It consists of 4 springs and a resistor. All out of veiw, inside the airbox. Remove the 2 screws and unplug the plug. Pull out the old resistor and replace with the new one. It only cost around $15-20 bucks at the local auto part store. This will get your fan blowing. If your fan is blowing but the air is not cold, I would suggest to check and see if the compressor clutch is working properly. If not, try giving it a light tap while running. If it is working, you may want to recharge your freon.

Chk for power at the blower motor electrical connector. If no voltage, check the blower motor resistor, its within the blower motor vent (this controls power to the blower motor). Also, in theses vehicles water may have damaged the blower motor itself. Inspect the blower motor for proper function.
