My parking brake warning light on the dash stays on but is very dim when the parking brake is off. You don't notice it during the day, it's only bright enough to see at night. The brake is all the way off and the switch is working fine. It will get dimmer once in a while and then go off for a while and then come back on again very dim. I'm guessing a bad ground is the problem.
Is there a common problem area? Where do I start?
