QuestionQUESTION: My security light goes through the proper squence when starting the car but comes on while driving. Usually stays on for a while then might/might not go out. Does not effect the cars performance. Thanks
ANSWER: NO. You have an intermittent fault. Check the computer for diagnostic codes.
1. Ignition ON. Engine OFF.
2. Simultaneously push and hold the OFF and WARMER (^) buttons on the climate control panel and see if any LETTER/NUMBER codes appaer as HISTORY or CURRENT and let me know what they are in the EXACT order in which they display.
3. turn igntion OFF.
