Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hello, and welcome to JA!! there are several faults than can cuse this to occur. the first place to start is to have the awd module scanned for codes. a trouble code would give us a better idea what the problem is.
If there is anything you dont understand, Please ask me to explain.
Can you get the AWD faults from the same location that the engine fault codes come from or is there a differant port?
