Gauge Cluster on 94 lhs

the gauge cluster (speedometer, tach, temp, odemeter, & gas) and my overhead navigator does not work. I noticed a little white smoke coming from the overhead navigator, maybe that has something to do with it. Everything else works great can someone please help. i ve got over 3k invested in this car and i dont want to give up on it

First check the fuses and then pull the overhead navigator appart and see what burned.

Thanx. that did it. the circut board on the overhead was bad and it was causing the cruise control fuse to blow. i just disconnected the overhead and changed the fuse and everything came back on
