I have a 95 Bronco full size that is giving me an airbag code of 21 which by looking it up is an improperly mounted safing sensor. Does anybody know where this is located to check it out? The code is not constant, only intermitent at start up. Once it comes on, it continues flashing the code. But the next time you start it, it may not flash the code. So I'm hoping that there's an intermitant ground problem with where the safing sensor is located, but I can't seem to find it. I've searched in the archives and have found no help yet. Anyone?? Thanks! I don't think that it's a clock spring issue as the horn works and I have tested the continuity at both ends of the clock spring leads.
