So I think my truck is possed it started with.

So I think my truck is possed it started with the front air would come on and off when it felt like it so I replaced the switch panel, the fuses, and the box under the glove box then the ignation switch. Still didnt fix it was told there was no power goin to the box under the dash so put a hot wire directly to it. Air works, since doing that rear air will not work and the head lights come on and go off when they feel like it. I can have the truck turned off and the lights will come on in the middle of the night and if they do that and the air is not in the off position then the air will come on and u will have to turn the air to off and press the small button beside the head light switch several times to get the lights to go off. Also the onstar lights stay on all the time and u will hear a clicking sounds
