Hi there. I have had a problem with my explorer's speaker that I cannot figure out. The Rear Passenger speaker goes out (no sound) every once in a while. I used to just turn up the volume and it would pop back on. I thought a cable was loose so i opened the door panel and they are fine and also behind the stereo. I just figured out that if I push the button to roll up the rear passenger window it makes it go back on as well. anyone know what could be causing this and how I can fix it?

Oh, I have an XLT 5.0 V8, the stereo is not a jbl but it does have a 6 disc cd change in the arm rest.

Thanks

The wiring coupler that goes through the door into the body may have a bad connection or wire in that area.
