HI i have been lurking through archives for about a week now but im still having my problem
all my interior lights work and function properly BUT
my clusters back-lighting will not turn on
I have:
-replaced and tested bulbs
-checked all fuses
-the rest of the circuit works fine
-i have tested my dimmer
-i have pulled most of my wiring out
Remember all the other things on the same circuit IE running lights ac/heater control lights work and dimm properly

for now i have the lights jumped to the accessory wire that powers the cluster but my lights basically stay on whether the headlights are on or off HELP PLEASE!!!
