Ok I am in big need of some help. I am working on an 03 cavi the gauge cluster quit working
It was replaced with a salvage cluster. This cluster worked for about 6 months then went bad
also. Sent the original cluster to the dealer for refurb got it back plugged it in and bam nothing. 285 bucks down the drain unless someone has some idea what else could be wrong. When hooked to a snap on Modis scanner the bcm shows no codes present. The IPC says no communication if that helps. And suggestions would be great.

You can check for a fuse to make sure it is alright, if the gauges were somewhat working before you put the new one in and the new one doesn't work at all you probably got a bad cluster or you forgot to plug the plug in. The only things I can think of.
