    If you are in reference to the fan speeds---then the most common problem would be the blower motor resistor. Some are real cheap and others not so much!! Good luck plowing and getting this fixed!!

    Just an FYI.... I had the resistor replaced about 8 times from Chevrolet because different blower motor settings kept not working... They finally replaced the blowe motor itself and that has been working rock solid now for the past 6 months... It used to only last about a week or two with the resistor being a replaced... just letting you know incase it doesn't work...
