I have an 05 6.0 Crew Cab Lariet. Lately iv been driving down the road and my dash cluster will reset, the chime goes off and the gauges do a sweep like when the key is turned on. It will do it randomly, bumps dont matter, it will do it idling at a light. It was a now and then thing and hadnt done it for about 3 weeks then yesterday it started doing it fairly frequently. This sucks! No loss of power to anything else except radio but it dosent lose the memory. I figured a loose connection to the cluster so i checked them and it was ok. Any ideas?? Maybe a bad cluster.

 

It could be a couple of things. On my truck, there is a relay that powers the dash and radio for probably 20-30 mins. after the key is off. If this replay is shorting, it could affect normal driving use also. It could also be a corroded connection in the GEM.

Next time it happens, check the operation of door locks and windows. If they aren't working either, it's likely the GEM connections, or the GEM itself.

When it happens at night the lights on the window and lock switches go out, ill check n see if they lose power, but its so quick just like a quick second. What is the GEM?

 

You seem to be right about the windows cutting out when it resets. Where is the GEM so I can try to clean the connections. Im not familiar with the GEM, never heard of it.

 

An 05 doesn't have a GEM module.

You either have a short in the wiring powering the cluster, or a bad or broken solder joint in the cluster. I would turn they key on and start wiggling wires back there and see what happens. You might have to pull the cluster out to get the the wires right at the back.

Yeah, I remembered that after I logged off. I verified the next morning on my own '05. I just forgot to submit a correction. Thanks.

Iv had my cluster out to check thoes connections as well, I think iv wiggled and checked every ground and wire I can find. Nothing I touch will make it do it... Im at a loss with it, Iv only had the truck since December of '11. I went to look at a cummins today and they offered me $16,000 for my truck. If the cummins wasnt a reg cab I would have already traded mine in. I love my Super Duty but electrical issues scare the hell outa me.

 

I don't remember the years affected, but there was an ongoing problem with the wire harness in the steering column. The issue was parts of the harness getting pinched and broken. Since your problem mimics turning the key off/on, might be worth looking at. I wouldn't doubt there might be a TSB about it.
