Power Windows
DESCRIPTION
The power window system allows each of the door windows to be raised and lowered electrically by actuating a switch on each door panel. A master switch on the drivers door switch bank allows the driver to raise or lower each of the passenger door windows and to lock out the individual switches on the passenger doors from operation. The power window system receives battery feed through a fuse in the Body Control Module (BCM) to the door modules.
The power window system includes the power window switches, the circuit breaker, and the power window motors inside each door. The power motors are similar in design and can only be serviced with the window regulators.
OPERATION
The power window system allows each of the door windows to be raised and lowered electrically by actuating a switch on each door panel. A master switch on the drivers door allows the driver to raise or lower each door window. The power window system operates only when the ignition switch is in the RUN or ACCESSORY position.
Front door window lift motors use permanent type magnets. The B(+) and ground applied at the motor terminal pins will cause the motor to rotate in one direction. Reversing current through the motor terminals will cause the motor to rotate in the opposite direction.
The power window switches receive battery from the Body Control Module (BCM).
