on the front passenger side and now i've noticed that the car isn't acting right at all. I'm suspecting that a grounding wire may be the culprit. But which one, I'm not sure. It's sporadic, but some of the symbols on the dash are flickering (anti-slip sign, rear window defroster) and the radio goes dead. The car shudders briefly also while all this is happening. I'm going to call an auto shop on Monday but any other advise is more than welcome!
