I was driving my friends 2002 Pontiac Grand Prix SE the other night and I noticed that there was no illumination of the headlight switch itself when the headlights were turned on. The result is you cannot see the switch inside the car at night. Is this normal? I pulled the switch and it is a sealed unit so if there is a bulb inside it, you can only replace it by replacing the switch unless you hack it open and can engineer your own fix. Your experiences?
