Relay clicking behind glove resulting in electric doors not working

[KingKong8247]

Well the title says it all. It started at Rausch creek. Hit a bump and this relay started clicking non stop behind the glove compartment but magically stopped after a little while.

Today I hit a kind of big bump and it started clicking again. No problem I figure it will stop. Drive home, turn truck off and it's still clicking and the doors won't all lock electronically.

I can lock them all individually but I cant lock them using the key fob or just pushing down the driver's lock.

Ideas?

A similar thing happened to me a few weeks ago. Driving on a dirt road I didn't see a pothole, hit it going too fast. The clicking under the glove box kicked in but in my case the hazard lights went off simultaneously. Once I turned off the ignition and restarted the truck it was fine. I posted about it here and the most plausible explanation was that the jolt triggered the inertia switch.

Try restarting your engine to see if that resets it.

could it be a problem with the "inertia"(?) reset switch in the engine compartment, on the fire wall behindthe glove box?

It clicked all night long. So I got in the truck drove where I needed to go and when I got
there it was fixed again.

I'll check out the inertia switch but it sounds like it's in the cabin.

It's not a bug, it's a feature...! There is another inertia switch and relay inside the alarm system housing which gets triggered if the vehicle gets bumped hard enough. Ostensibly, this is to automatically turn on the hazard flashers after a collision. Some trucks just have a lower threshold than others for this activation to take place. Turning the ignition off, then on, then off again turns off the flasher circuit.
I've considered putting a switch into the circuit that supplies juice to the relay, but it's A) in a cramped, hard place to work, and B) not clear if there might be unforeseen issues with the alarm system and engine lockout.
