So I have seen other posts about this issue and the likelihood that moisture has gotten down into the wiring harnesses but how do I know that for sure? I mean without taking apart all the doors? And to correct the problem, I'm not sure that it's worth it if I don't replace the seals around the windows. All I'm getting right now is sound from the two door speakers on the driver's side and a little bit of a buzz in the tweeter on the passenger side. No rear sounds at all. I've tried fade and balance and all of that so any suggestions to be helpful.
