My '02 Burb is losing the back lighting on the Heater control and the driver door power window switch. Do any of you know someone that can repair these parts? I priced new ones and they aint cheap... My radio lost the lights and the local audio store was able to fix it however they didn't have a way to repair the switches. I did try a couple salvage yard units but they had the same issues with liitle to know lights functioning to illuminate the switches/controls at night. thanks for your replies.
