I've got one from left field for the forum. The night time illumination on the driver's power window switch is out on my newly acquired 2002 Suburban. For a while, I could bump the door panel and part of the lights would come on. Now none of them come on. I checked and am getting 12 volts to the proper pins. The question is: has anyone taken one of the switches apart and replaced the bulbs or LEDs? I routinely take switches apart on my Mercedes Diesels and refurbish the switch contacts rather than buy new switches.
