Yeah, I have a problem with both left door speakers not working. Intermittently they will work then stop. I've tried a different radio in case I lost part of the output on the old one but the problem persists. I've just not taken the time to tear the doors apart to check the connections yet although it makes me wonder if the problem isn't further forward as they both go out and come back at the same time.
