Hi, I just purchased this big, beautiful car and the only window that rolls down is the driver's window and they also don't roll down from their own switches. The passenger door panel is off, and I'd like to hotwire the window motor just to make sure it's not the window switch or bad wiring. It has a red and a yellow wire going to it. Thanks.

Also, the other thing that doesn't work is the heater blower motor, just in case if that might be connected.

These are separate problems please start a new question for the blower motor. You can connect a power and ground to the motor to hot wire it, please reverse the polarity if it does work in case the window is all the way down in which case more down will not make the motor work. Let me know what happens, we don't have wiring diagrams for a car this old, sorry.

Yup I've done all I can, I believe it's dead. I'm going to attempt to pull the motor apart and maybe clean up the windings and brushes, thanks.
