Hey guys, need some help here. I've got a 2001 Silverado extended cab 4.8L pickup and I have a problem with my heat and AC. I have a control knob from 1~5 for my heat and AC but I get nothing from 1~4, just 5 works and thats on high. Is this a control problem or a blower problem? Any help would be appreciated.

There are couple threads in the Tahoe section about this kind of a problem. What fixed theirs was replacing the resistor on the back of the blower motor, maybe it will work for you.

Thanks for the replies, after some google searches I found it to be the Blower Motor Resistor. $28.00 and 10 minutes later it's all fixed up.

That seems to be a common problem.

...it is a common problem because it is a throw away part...as it is used it slowly destroys itself and will need to be replaced every do often
