I need help, I have a few warning lights that keep coming on and off, they are the engine light, airbag, ABS, Track off and sometimes the oil light. Some times when I start the engine the serv error warning appears in the odd window. Its very intermitient. The other thing is if those lights are on when I start, then the A/C wont work but if the A/C is on and the lights come on the it still works, I know this sounds crazy but thats whats happening. I have had an LS1 Edit done I want back and had t checked and was told thats not whats causing the problem. He said it might be in the Body control Module. I'm hping someone out there can help.....
