Hello, i have a 2000 gmc, 4wd. recently, the dash cluster has been acting weird... all the gauges turned off when i went over a bigger size bump. a few days ago, i went to turn on my truck, and all of a sudden; No gauges, or stereo. Anyone know of a fix for this? i replaced the cluster, and that wasn't the problem. Thanks. (The oil pressure and volts gauges are working, and the reading lights and dome lights are NOT working.)
