2002 GMC Yukon 4x4, 5.3L Flex.
2 months ago the blower motor stayed on after the key was shut off. I disconnected the battery for the night. When I reconnected the battery, everything worked fine.
2 months later, I'm having the same problem. Disconnecting the battery made everything work again, but a few hours later the problem came back.
The blower motor stays on high all the time (even with the key off) and no climate control adjustments respond.
Anybody know how to troubleshoot if the problem is the Heating and Air Conditioning Blower Control Module or the Heating and Air Conditioning Control Panel? Or something else....
Thanks!
