Greetings to all from a newbie with a strange question. I have a 07 Silverado LT with power windows,locks,etc. As you know the door panel window switches are illuminated when the head lights are on. I noticed the while driving last night the driver door panel lights would go out and flash on again after a few minutes. While stopped at a red light I could here a faint clicking noise coming from under the dash that corresponded with the door panel lights going on and off. All other lighting on the truck is normal. In the owners manual there is a description or a number of replaceable breakers. Could one of these be failing causing the flashing? If so I can I tell which one goes to the drivers door window panel? I have checked for frayed and broken wires to no avail. Any help would be appreciated.
