Power window switch

The individual power windows are controlled by a two-way momentary switch mounted on the trim panel of the passenger side front door trim panel and, on four-door models, on each of the rear door trim panels. Two-way momentary master switches on the driver side front door trim panel control all of the power windows in the vehicle. The driver side front door trim panel also has a two-position power window lockout switch.

The front door power window switches and the power window lockout switch are integral to the Driver Door Module (DDM) or Passenger Door Module (PDM), respectively. The rear door power window switches are stand-alone units.

Each power window switch controls its power window motor by switching battery current and ground between the terminals of the power window motor.

The passenger side front door and, on four-door models, both rear door power window switches receive their battery feed through the power window lockout switch or through the master switches in the DDM.

Also, each of the individual power window switches receives its ground through the DDM. When the lockout switch is placed in the Lock position, the individual power window switches become inoperative because they have no battery current available to them. However, the master switches are unaffected by the lockout switch position.

Each power window switch, except the lockout switch, is illuminated by a Light-Emitting Diode (LED) when the ignition switch is turned to the On position. However, when the power window lockout switch is placed in the Lock position, the LED for the locked-out passenger side front and, on four-door models, the rear passenger door power window switches is turned off.

The front door power window switches and their lamps cannot be repaired and, if faulty or damaged, the entire door module must be replaced. The rear door power window switches and their lamps cannot be repaired but, if faulty or damaged, only the affected switch unit must be replaced.
