Dash doesn't work and weird electrical problem

Noonman350 · May 13, 2015

So I just got my truck back together after an oil pan fix, and I'm having two issues. When I got it started, I let it idle for a while. At first I reved it up and all the gauges on the dash were working. I let it sit, and came back out to the shop and nothing works. No RPM gauge, battery, temp... Nothing. I've also had a weird electrical problem. There is a clicking in the can and a buzzing sound sometimes from under the dash. Also, my headlights turn on and off unless I have them on. In that case I just get the clicking sound. Any help would be great, thanks!!

Double check all electrical connections.

Same thing happened to me, cleaned my battery terminals and everything was fine.

Battery connections are clean, and I sprayed all connections with electrical cleaner. I should have checked the fuses first but I was tired. I'll check after work

Spray will not clean battery connections. Brush them off with a wire brush until they shine.

Check and clean all electrical connections. I bet most of them have not even been looked at since it was built.

I sprayed and cleaned them with my battery terminal brush. I'll do a once over on the connections with the cleaner. I thought I got them all when I pulled the motor. But I might have missed a few

I have seen the windshield leak water and drip on the GEM module and fuse box causing all kinds of havoc. Just a thought.

Got the gauge cluster to work. But I'm still having this weird electrical problem. All the lights in my cab, my tail and head lights all click on and off and a clicking sounds like a relay. If I turn the lights on, then the clicking stays but the lights don't flicker on and off.

Never mind. The instrument panel went out again.

With a combination of instrument panel and lights I would be leaning towards a leaky windshield issue. Do your radio and blower act up also?

If it'a an auto, the wires going into the shifter can short out by rubbing on the column and cause instrument cluster problems.

It's a manual. And it's been in a shop for the last 6 months, so I don't think leaks in the windshield could do it. But I don't have a radio at the moment, but when the instrument cluster turn off the windows won't roll down either
