Electrical / HVAC Ground Question??
I posted a few weeks ago about the HVAC circuit that would not turn off with the key in the off position, it continued to run. I replaced the blower control module and it did not fix the problem. Someone told me that GM switches the ground circuit to control the HVAC. Is this a possibility, could I have a shorted ground wire? Also, I am having some strange things happening with the “Driver Information Center” and the Traction Control switch not working. Any ideas where to look for some shorted ground wires, or any common place where I could have some wires rubbing?
Thanks for the help
