hi, i know this has probably been done to death but i cant find an answer. is there any way to fix the problem with the climate control bulbs that illuminate the switches. i have changed the bulbs and the head unit with one from a 2004 model, but i still cant get the switches to illuminate. is there a common fault with the pcb in the unit? do i just keep looking for a scrapper with a unit that works?

Turn on the lights and check for voltage across pins 4 - 5(red/brown - back wires) of C0791...if no power we'll speak again provided you have decent skills with electrics
