CHEVY INSTRUMENT CLUSTER

2004 Chevrolet Trailblazer

Electrical problem
2004 Chevy Trailblazer 6 cyl Four Wheel Drive Automatic 104000 miles

This is a known problem with the 2004 trailblazers. First, the RPM gauge stopped working, then the oil gauge, now it's the fuel gauge. I know we have to replace the instrument cluster, but need instructions on how to do that. There's no recall on it, so getting chevy to replace it just won't happen.

I can give the instructions, but be aware that the cluster needs to be programmed. It may have theft information to relearn, or at a minimum the odometer and engine hours need to be installed.

Instead of replacing your cluster consider having it rebuilt instead. It would be a lot cheaper and easier in the long run because you wouldn't need to have any reprogramming done.

You can get information on rebuilding it and simple removal instructions here - http://www.drspeedometer.com
