Possible short-electrical problems? Olds Bravada 43000 miles!

Problem started about a month ago-airbag light flashed and I felt "something" when braking. Then, Bravada started stalling when braking. Cleaned (Husband, not me) the throttle body, cleaned the EGR, no faults when hooked up to the Snap On computer, changed the plugs, fuel filter, etc., Car "runs" like new, solid engine idle, but when driving to work today, the radio was off, turned it on, heard a noise, and the air bag light flashed. Driving home from work, all the dashboard lights flashed, but the car continued to run just fine. What else can we look for? Bought a new SUV, and need to sell this, but want it to be in a little better condition?{Po

Check you conections to the fuse box. make sure that it is not crossed on the wiring and that the wiring going thru the fire wall is not cut.

What year?

Could be a bad connection at the battery, faulty ignition switch

Your right merlin do it twice and then relize that you could have done it right the first time with less money. Funny thing. As for the wiring. There is a problem with the bravadas that comes up alot. Thats the wiring harness on the puter. Check that also. It goes around the metal bracket from the side and it wears there alot. Just look where the wire harness goes and youll see where it goes over the bracket. Check for worn wires there.
