Last night the parking lights and instrument panel on my 2005 Caravan started flickering on and off while the headlight switch was in the off position. It happened with the car running, and also after I turned it off and locked it. As I was walking away, the lights were still flickering. I went back and played around with the headlight switch, and they finally stopped flickering. Would this be a switch problem, a relay problem, or a computer problem? I'm hoping just a switch. Thank you!
