I have a 1994 Chevy 1500 I plugged in a different trailer @ my rear running lights tag lights@instrument cluster lights quit working. I checked the fuses all seem ok.

check the computer on the car it happened on our 91 chevy lumina euro and when we changed it it fixed the problem

Check all the "spare" fuses in the fusebox. replace any that are empty with the proper grade fuse. If it pushes in like it's connecting, that may very well be your problem. If it just slides in and out, the slot is unused, and therefore, "spare".

Pretty common problem with these. Here's a guide to learn how to fix GM instrument clusters yourself, I used it to fix mine and it worked great. How to guide for Silverado instrument cluster repair

Well, that sucks, for sure. The only commonality I can see between the engine, abs, brake light and speedometer is possibly a bad vehicle speed sensor. But when you throw in the codes for lost comm and cluster error, that muddied the water a bit. I am sure that there are separate fuses for the trailer wiring harness (my 04 chevy has separate fuses, surely an 09 dodge does) so I doubt trailer wiring could have done all this. A lost comm could be caused by a blown fuse. I would inspect every single fuse I could find in the entire vehicle, also, I have researched your problem a bit and have found a couple possible fixes. One is that the abs sensor on the rear differential is known to be sketchy and needs to be changed. The other is cleaning any ground cables that are connected to the fuse box on the front left fender. I hope this helps!

did you check the fuse?
that sounds more like the problem!!!

Hello Ron Sadora, Your cluster is totally digital.. Mike www.kincerservice.com

The stepping motors in the gauge go bad, but uusually they fail gradually, or just one, The dealer charges $300 to fix, do a search on ebay for CHEVY SILVERADO INSTRUMENT CLUSTER for cheaper repair options. gauges are powered by the pcm, no fuses inbetween, so if it runs ok, problem is in cluster
