So I just bought a 95 jimmy 4x4 the other day. The 4x4 buttons worked, and so did the dash lights. I put my new deck in today and now my dash lights and my 4x4 buttons don't work ? I checked the fuses and there not blown. My headlights and signals all work. I will double check the fuses, but I'm pretty sure that there fine. What would cause this ?? Please help me out here asap !

The harness for the 4x4 switch run right behind the deck. It'* possible you may have pinched the wires by pushing the deck into its final mounting position. Pull the deck back out and verify that you didn't pinch any wires.
