03 silverado dash cluster

Very common problem I believe.

Low voltage will cause temp dash failure. I had a battery drain and ended up with dead gauge cluster. Upon recharging the batteries, all was OK.

Also there is a company in Concord Ontario (among others) that reman's dash clusters for a lot less than buying OEM. ddinstruments.com

Google gaugecluster and you'll see the '03 come up.

Good luck. I've been fighting a phantom electrical draw that is very inconsistent on my '03 GM Dmax.

Rebuilt gage clusters are redily a ailable on the internet. There are a couple of known problems with them. Just replace it.

I think I would try the tighten and clean before I paid big bucks for a new dash cluster. Have you priced a new cluster, will make your teeth fall out when you find out how much they are. I had one replaced in my '98 and glad it was under warranty.
