Hi I have read all the threads about the airbag beeping because the light was burnt out, but in my dads 99 f350 the airbag light comes on when cycling and stays on during and after startup. It came on yesterday but this morning it beeped two sets of 5 beeps. The OFF light for the passenger airbag also is still illuminated when in the off position and not when in the ON position. What do I check now? The clockspring? How do you get to it?
