Has any one had there air bag light come on for no know reason. I started my truck this morning and there it was bright yellow. I can also hear a clicking nose. It sounds like a switch. Seems to be coming from under the dash board. Here is the odd part:the keys are removed. I turned off the passenger side and the light stayed on with the engine off and the keys in my had. If any one out there has any ideas, I could use the help.
