Don't know about the bag, but that clicking sound is likely the relay working correctly. Either your horn (horns?) is/are shot, or the wiring leading from the relay is. Just my guess from what I've read on the forums

Sounds like the horn itself is bad. It is located under the passenger side of the bumper cover. The clicking you here is the fuse/relay working.

You're supposed to get your airbag inspected every ten years at the dealership. I'm almost positive it's free.

Yes sir. It's not something that is supposed to be done by a local mechanic. Won't hurt to give them a call and verify.

Swap in a new horn from a junkyard ZJ, it's only two bolts if I remember correctly.

do you know if the horns/&horn circuit are different between the 4.0 and 5.2 grand cherokees?

Before replacing the horns.... Push the horn button and make sure you have 12v at the horns... make sure the ground is good.

There's an impact sensor behind each front bumper corner. Make sure the connectors are seated properly. My 94 came from the factory with one connector only partially plugged in. A few years later it came loose and the airbag light came on.

Clicking sound is the normal horn relay sound located below a panel in the bottom of the glove box. Just because the relay clicks properly, it could still be bad. And even if the relay is working, doesn't mean the 12v is making it to the horns up front.

You can swap the relay with another one to test it... and also check for 12v and ground at the horns.

My jeep was doing the same thing, then one day it just randomly came back on. I'm sure it's partially plugged in, i'll look at it one of these days

I was thinking on doing that, and wish I had, I may still do it.
Train horns are a little extreme though.
I would like to find a reasonably priced one , that's LOUD
I was at the JY anyway so grabbed some for 5 bucks

What sensors? The airbag sensors? Theyre only relevant because the airbag sensors and the horn wires and bundled together to the front right of the jeep, it's literally directly under your passenger headlights behind the plastic bumper.

If you are in fact looking for the airbag sensors, there are two of them(one on each side) of you actual bumper underneath your plastic bumper.
