Can you stand another question about the power windows? The right window has ceased working, at least in the down direction. I replaced the motor, but that was no help. I've tried all the switches in all the positions, even getting a set of switches from another car, no help. If I take a jumper and switch the voltage on the motor connections, the window will go down, then if I put the wires from the switch back on, the window will go up, but it won't go down from either the left door switch or the right door switch. Another oddity (I don't know if this is related) is that the left mirror will not go in and out with the electric adjustor, just up and down, and the sunroof has stopped working. I have checked for voltage and ground as best as I can at the switches and so on and can find nothing wrong. I have been thinking that I could wire in a rotating switch to the right door that will allow me to switch the voltage when I want the window to come down, then back when I want it up. Do you think this would work?
