Z71 dashlight problem

has anyone else had problems with the dash lights not working at night and working during the daylight. at night when dash lights are out i can push dome lite switch 4 times and everything reverses. headlights go out and dash lights work again. the transmission lights and dimmer light work all of the time when key is on.

the headlight switch dimmer assy is defective. common esp. if after market type stuff uses the dimmer switch .. the shift indicator is different circuit.

chevy dealer says it's the BCM(body control module). 600.00 for part 400 labor. think i'll try other things first.

He didn't say after market stuff made the dimmer switch go bad. Just that it could. I'd go with replacing dimmer switch.
