Question about 1999 Chevrolet Silverado 1500

Air and fan control

I have a 2003 Chevy Silverado. Recently my fan controls went out on setting # 1,2 and three. Today, my #4 setting went out. Any ideas what the problem might be and if it is something that can be fixed at home rather than at the dealer?

You have a reostat that is located in the blower motor housing it will have a 2 wire lead to it it's helld in place by 2 screws this is what regulates the fan speed. this should be replaced ..please rate the solution...thanks

The problem is the heater/ac control module itself. pop off the face plate that covers it. you can then pop out the controls.

Had exact same problem with my 2006 Chevy Silverado 1500. Would blow hot air thru drivers vents only and sometimes if I turned truck off and restarted would blow air conditioner for a bit. Rec'd recall letter from Chevrolet in January for this problem.

there is a resistor that controlls the speed of the fan and you have to replace it it is located where the plug goes to the fan motor it should have two plugs in it one from the controlls the other goes from the resistor to the fan it is a dealer only item it costs around 89 dollars check different dealerships if you have more than one close by the price will vary my 2006 chevy silverado work truck lost the 1 and 2 speeds then others and it was freezing out and i replaced it and have not had any problems since inspect the wires i had two wires and one part of the plug melted on mine went to junk yard and got a new plugg for under ten bucks dealer wanted 117 dollars

2003 chevy silverado air does not blow through vents. Condenser works. Pipes are cold. Fan works. Modular (next to fan) repalced to get fan to work. Heater air conditioner controls under radio replaced....


The air vents are control by vacuum line and or linkage.

Listen for hiss or feel for vacuum leak under the dash,

Feel for broken linkage(s) that are close to the vents.


WORK BACKWARD if you have small hands to feel out where is the missing link.

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 .

Chevy steering wheel controls


You first have to disarm and remove the air bag (unscrews with bolts from behind the steering wheel) and then you will see the screws for the switches. Only the silverado awitches will work.
