The speakers in my Loyale occasionally go in-and-out, or give a buzzing noise when sound goes through them; this all mostly happens on the passenger side. I have noticed that when I press certain buttons in the car, it affects the speakers, sometimes causing them to start working normally. This is what has had an effect: Pressing the 4wd button (not even all the way), adjusting the electric mirrors, raising or lowering the passenger-side window, and opening/shutting the passenger door (it may be the seat belt that does it). I have replaced the speaker in that door, and the problem has not changed. It was working fine for several weeks up until recently. Anybody have any thoughts? Thanks!
