1994 Chevy K1500 Dash Lights Out

Suggested Repair

Check the wiring diagram for everything on the blowing fuse circuit and test each circuit for voltage and ground. Because the dimmer switch gets hot, inspect or replace the dimmer switch and check the steering column wiring; correcting one circuit may resolve related light problems.
