i have a 2001 gmc Sierra 1500 Z71 with a 5.3...for the last month my dash lights switch off when my automatic headlights turn on or when i turn the switch on..the used to work when i locked on the dimmer switch but that has stoped working..i have check all the fuses that i can find and they all seem fine...the only thing i have done with the lights is add cab lights on the roof of the cab. any ideas? im tired of driving at night with my cellphone light, lighting up my dash...lol
