Ok...here's the latest update...

This morning (6:00am/dark out) my my car was running and I jumped out to run into some place...when I came back out and got in the car I notice the gauge lights 'very' dim. So I shut the radio and heater off and they got a little brighter...when I accellerated they got a lot brighter but dimmed slightly when I stopped again...over the next 30 minutes of driving they got back to where they should be and I was able to turn the heater back on and the radio...got home...car off for about an hour...came out, started right up and everything was operating normally???

Could this be caused by anything you guys have suggested?
