Dash guages stop working...help
 

I have a 2003 GMC Sierra HD Crew Cab with 88K miles on it. After purchasing I lifted it with 37" TSL 20s with a few aftermarked mods. Putin stereo w DVDandTVs in the headrests...
Then it got broken into and all was lost. A couple of months when by and my dashguages including tach. gas speedo. tran temp. would stop working periodicaly and then come on at any time. This was alright but now nothing comes on, ever. Ive checked for fuses, bent or messed up wires, but still nothing. Oh ya, my blinkers and hazards still work. Please help.
