Thanks for your reply, I disconnected the battery overnight, didn't change anything. I checked the plug behind glove box seems fine, I then removed the infotainment part from dash, disconnect both plugs they both look good then made sure they were plugged in tight, still the same. I do have a code reader it shows code p0481 - (fan 2 control circuit) this code came a few days after this problem started, it seems to me it might be a power supply issue, even the OnStar is not working.
