Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is***** you have automatic or manual controls? Thanks.
This most likely means the blower motor control module has failed. First verify blower will work when manually applying power/ground. If good verify black wire has good ground and red wire should have good power at blower motor control module/processor. Here are replacement instructions, let me know if you have more questions. Thanks.
