I have a 1994 Chevy Silverado 4x4 6.5 diesel. The 4x4 fuse keeps blowing and then my speed gauge and tac gauge went crazy and blew the gauge fuse.
Sounds like a mouse has got in and chewed the cables,their is no easy fix from what i can think of but check all the wires and connections in case water has got into it,or snow if your in alaska.its fifteen years old now so its possible that some insulation has broken down or a wiring loom has chaffed somewhere underneath
