Power Window Motor: Description and Operation

WINDOW MOTOR
The power window system allows each of the front door windows to be raised and lowered electrically by actuating a switch on each respective door. A master switch on the driver side door trim panel allows the driver to raise or lower each of the front door windows.

The window lift motors are of the permanent magnet type. A battery positive and negative connection to either of the two motor terminals will cause the motor to rotate in one direction. Reversing current through these same two connections will cause the motor to rotate in the opposite direction. Each motor is grounded through the master switch.
