I have a 2004 tj sahara. Every once in a while, when i crank the jeep up, the airbag light comes back on and the blower motor for the a/c doesn't work. I know the a/c is coming on. Seems to be an associated problem with the blower motor and the airbag. I checked the airbag fuses and one of them has 12 volts dc and the other doesn't. I checked the blower motor fuse and it has no voltage to it either. Also, If i take the blower motor fuse out the light for the airbag goes out. Could I just have a bad fuse causing this problem or could it be something more serious. Please help!!!!

just in case anyone wants to know it was the ignition switch that was bad. I replaced it and the problem went away.

Thanks for the update, im sure in the future this will help somebody out there.
