Hello, My name isXXXXX will do my best to assist you.

Up under dash on right side is the blower motor and next to it the blower motor control module. When this happens, 99% of the time the module has failed.

We have replaced quite a few over the years in several different GM models. They fail and the first sign is blower will not shut off even with key.

Not hard to change, A couple screws and a plug and it slips out of the case. #6 shows it in the picture
