clicking noise in dash?

Hi guys, haven't been around here in a while, got to be spending too much time on-line etc.
Anyway,
I got my Grand G'neer on the road for the summer (finally) and now I remember that I've had a strange clicking noise in my dash for a while now, (years) that was really bugging me this weekend.
It sounds like a relay clicking or a small solenoid etc. that what ever is tripping it, is making intermittent contact like a loose wire jiggling over bumps or something. Imagine dragging a live bare wire along a metal surface making sparks etc, and how a relay or solenoid would react. The noise sounds like it is coming from behind the gage cluster, while sitting in the drivers seat.
What system in an 87 Grand Wagoneer would have a relay/solenoid that would be mounted behind the dash?
Everything seems to be working properly, (except the gas gage, it drops really fast from full) the gages don't jump, lights don't flicker etc. when the noise is happening. does it with the lights on or off. horn works with the ignition on along with the cigarette lighter.
At this point it is only a noisy relay that seems to be doing nothing?
Any ideas?
Thanks,
baja

Does it doing only with the car moving, or also when it's sitting still?

Oh, and your gas gauge is working fine, these things really do get that kind of mileage...

If it only happens when you are moving, I'll bet its your speedometer cable. Reach up into the dash from below and you can unscrew the cable from the cluster...then pop your hood and pull it through the firewall. From there just pull the speedo cable from the housing and put lots of graphic based anti-seize lube on it....put it back together and you'll be all set.

It's not the speedo cable, mine does make noise after the Jeep has been sitting a while, but quiets up down the road. The noise the speedo cable makes is constant cyclical noise related to vehicle speed.
My dash noise only happens when the Jeep is running, either going down the road or even like when slowing to a stop and sitting for a stop sign.
It is a random clicking that can be quite fast and very inconsistant, like a solenoid getting a poor contact. The clicking noise is about as loud as a computer keyboard, key click. Just enough to hear it over vehicle road noise.
What all solenoids/relays are there behind our dashes?

Not any that I can think of. It may be something that a PO added.

There is no way I could ever hear a clicking noise under the dash. My 258 makes so much noise that I don't even use the radio. However if I did have a noise like that I would just turn up the volume of my radio and call it done.
