A strange electrical issue.
The last couple of weeks I've ran into a problem that I can't even begin to diagnose. The car starts without a problem but the lights are dim. The blower motor seems like it won't go past low even when on high and the radio turns off. Yeah, alternator or battery issue. But once the car warms up after driving everything is fine. It has turned off twice on me when I let it idle before driving requiring a jump. I've never ran into a problem like this before and I honestly don't know how to test for it. Any ideas?
