I keep getting a service air bag light only when it is cold out. I've replaced the front air bag sensor (the 3500's do not have side sensors that I'm aware of), and cleaned the ground by the front drive side frame. What gets me is this comes on intermittently, but if it does it's less than 40*F. It really likes to do it when it's single digits in the winter. Sometimes it will go out while driving, other times it flashes on and off every 10 seconds, and others it stays on the whole drive. Once in a while when cold it won't come on at all. I have never had it come on when it's more than 50*F outside. This intermittent behavior makes it really hard to tell if anything I do either fixes it, or being able to track it down.
Any suggestions or starting places?
