SOURCE: A/C and Heater Only works on the highest speed

The blower motor resister is bad...It is very common in chevy trucks. The resister is located behind the glove box and is held in place by two screws, it will also have a wire harness attached to it. If you want to see a picture of it go to www.partsamerica.com and search for the blower motor resister.

SOURCE: Heater/ac switch speeds 1 and 2 don not work in 99 Silverado

you need a resister found under your air duct by the passenger floor under dash board auto zone sells these for about 25.00 you may as well buy cabin air filters while your at it . 1 of the screws will be a pain to install back into the duct work I left mine out didn,t make a difference . you might have to order it as they are a comman item oh you will need a vacuum to clean up mess from cabin air filters .this is not a hard job .

The fan on my heater/ac stop working on settings 1-4 for awhile it worked on #5 but has now stopped altogether


The blower resistor has gone out but if blower is no longer working on speed 5 then either the blower motor is bad as well or the pigtail connector to the motor are bad. Check the plugs to the resistor and to the blower motor for insulation damage discolored or melted wiring.

Climate switch will only work on 5


The fan resistor is under the right side of the dash at the bottom of the heater case. on this car they generally fail because of a water leak into the heater case. The leak will have to be found and fixed, or you will burn another resistor out if you replace it.
