05 V6 Mustang Weird Electrical Problem(s)
I'm having electrical problems with my car. Last night as I was driving home, the headlights, dash lights, A/C instrument panel backlights, interior dome lights and all just shut off. I quickly pulled into a parking lot since I was driving blind. The car still ran, my tach worked, and my temperature gauge worked, however my fuel gauge was reading empty(with a full tank). I checked the relays under the hood, and swapped out both pcm's with like relays to try to limp it home, however that had no effect on the lighting issue. I then started to dig into the fuse box on the passenger side floorboard kick panel, and then big latching plug that is above the fuse box. Suddenly everything came back on when I fiddled with it. So I proceeded home again, and 5 min later the lights cut back out. So I was in square one again. I fiddled with that plug, and everything came back on, and I was able to get home. Now here's the kicker, once I was home, I turned on the headlights and the interior dome lights and unplugged that plug, and everything stayed on. So I'm lost on this one guys. And I don't really feel like paying the dealer $500 for an easy fix. Any Help?
