The rear bumper tap is not related to any airbag/SRS components.
The SRS system is comprised of a few parts and the clock spring may be the issue. It could also be the control module or the actual crumple sensors on the vehicles structure.

Most owner's manuals advise to have the dealership check the SRS diagnostics after 10 years.

As your brand of vehicle is not know for great "electrics" your story is common and may require a bit more digging around than is typical.

Good luck.

My husband called me the other day complaining that the airbag light on the dashboard would intermittently turn on and off while driving the car. Sometimes the light will stay off for a week at a time, but other times, it will repeatedly flash on and off throughout the entire trip.

Two or three days before this happened, my husband backed into a mailbox and it left a small dent in the plastic bumper, which my husband pryed out that same day.

I've done some research, and I've heard that the clockspring is a VERY common problem in the 1999 Jeep GC, usually going out around 100,000 miles, but the proximity of the dashboard light to the mailbox incident has me wondering. Also, with the airbag light on, the horn and the cruise control BOTH work.

Is there a sensor in the back bumper that (if dented) would cause the airbag light to flicker on and off? And if so, how would I go about fixing it? What (other than the clockspring and maybe a fuse) would cause this problem? And is it possible for the clockspring to be broken, but the horn and cruise control function normally?

Any help is greatly appreciated, but please don't tell me to take it to the Jeep Dealer. $108 to put the truck on a computer and read a trouble code is absolutely ridiculous. I'm just looking for advice from Jeep owners and mechanics who may have had similar problems with their truck in the past.

Thanks again!
 
ya definatly avoid any jeep dealer most are about as idiotic as the engineers building jeeps now adays. being a 99 it is obd2 so you can try bringing it to advance auto parts and have a scan run for free. it does like a sensor is messed up. i would recommend getting a haynes repair manual for your vehicle.

after dealing with my mas 2000 wrangler i have decided i will never own a jeep newer than the old cj7's prior to when cryshler bought them and ruined everything.
