    I'm having trouble getting my passenger side power windows, lock and mirror to work. I replaced master control switch, checked fuses and wires...no problems. And all I did was disconnect my aftermarket door speakers and run them directly to an amp.

    If the power supply goes thru the door there might be a wire break where you are not getting power to the doors from years of opening and closing. Finding a broken wire there could be an issue as the break would be underneath the insulation. See if you can get at switch that operates the window and check it for 12v with the key on. If you can get at the wire harness look for a red wire as that means it is a constant power source, the red with white tracer is a switched power source.

    Well, that is a start. It is still possible to have a broken wire underneath them. As another suggestion, you could remove the door panel and try to activate the window motor with a 12v hot line from the battery. This might help you trace where the problem is located. Or you could try to find where the circut break is actually at with a voltage meter and piercing the insulation with a straight pin connected to the voltage meter. This is assuming that the problem is a broken hot line to the window circut.

    Could be an internal wire break that connects with closing of the door. Try opening each door one at a time and jiggling the wire harness to make a broken wire connect to find out which door is causing the problem. I use the word could loosely, but it has to be something.
