Relay failure? (electrical problem)

I have a 99 GC with an electrical problem that started three days ago.

On three occasions when I turned off the ignition (after driving) the power to the interior electrical system failed. It wasn't completely dead. There was a constant clicking sound that seemed to come from under the dash occuring around 2-4 Hz. The dials on the instrument cluster were moving randomly. The light under the driverside dash was dim and flickering at the same frequency of the clicking sound.

Except for the random movement of the gauges and the clicking sound, the vehicle behaved as if there was no electrical power. Actuating the RF remote had no effect either.

This first happened when I arrived at a local Target store. I went inside to shop and when I came back out 20 minutes later, everything was back to normal. I started the Jeep and drove home. Everything worked fine. The clock on the radio did reset though, consistent with loss of power.

Any help is appreciated.

I would start by checking for loose or corroded battery connections.

The battery connections are clean (no corrosion) and the cables are solidly attached. When the problem's not occuring, the battery power is strong, starts the car without problem, and everything functions fine.

I had something similar going on when one of my taillight sockets shorted out. I think it got wet. Just check if all your lights are working.

Life is short. Play hard.

Thank you for the suggestion. I'll check out the lights. It's been 4 days since the problem last occured. If it was due to some moisture causing a short, then maybe the problem has, for the moment, cured itself.
