Question about 2001 Chevrolet Silverado 2500HD
Hello, I have a Chevrolet 2500HD truck. The heating and a/c control that determines how hot or cold the air is seems to turn fine, but sometimes, the heat will run you out of there. You can turn it as cold as it goes, but the air is as hot as it gets. The only way to "fix" it seems to be to turn the key all the way to off, let it sit for a minute, and re-start the truck. I know it is all electronis, but are there any ideas on which piece the "re-setting" of the electronics is fixing? I guess there are several electronic controls involved there Thanks for any advice, Scott This issue of cooking you out of the cab just started happening. If you turn up the heat to warm up the truck then it is stuck on HIGH TEMP. Turning it to cool or turn on the A/C with maximum COOL does nothing but turn on the AC unit and remove moisture at HIGH heat. If I turn off the Truck, turn temerature to cool it is instantly bringing cool air. Turn on the A/C and MAX it is VERY cold. Move desired temperature back to medium or high and the oven starts cooking you again. Also, why if you turn the FAN OFF, does is still blow some air? It seems that there is three solutions being posted with this common problem.
The temp control is vaccum ran not eletric so look for broken vaccum lines under dash or bad vaccum controler
