Description and operation

Power window switch

The power windows are controlled by four two-way switches and a power window lockout switch that are integral to the power window and lock switch unit on the driver side front door trim panel. Additionally, each of the passenger doors has a single gang twoway power window switch mounted in a bezel on their respective door trim panels. A light-emitting diode (led) in the paddle of each switch is illuminated whenever the ignition switch is in the on position.

However, the leds for the passenger power window switches are extinguished whenever the driver selects the lock position with the power window lockout switch.

The power window switch for the driver side front door has an auto label on it. This switch has a second detent position beyond the normal down position that provides an automatic one-touch window down feature. This feature is controlled by an electronic circuit and a relay that are integral to the driver side front door power window and lock switch unit.

The power window switches control the battery and ground feeds to the power window motors. All of the passenger door power window switches receive their battery and ground feeds through the circuitry of the driver side master switch unit. When the power window lockout switch is in the lock position, the battery feed for the individual passenger door power window switches is interrupted.

The driver side power window and lock switch unit and the single gang passenger door power window switches cannot be repaired and, if faulty or damaged, the entire switch unit or switch must be replaced.

Power window motor

A permanent magnet reversible motor moves the window regulator through an integral gearbox mechanism.

A positive and negative battery connection to the two motor terminals will cause the motor to rotate in one direction. Reversing the current through these same two connections will cause the motor to rotate in the opposite direction.

In addition, each power window motor is equipped with an integral self-resetting circuit breaker to protect the motor from overloads. The power window motor and gearbox assembly cannot be repaired and, if faulty or damaged, the entire power window regulator assembly must be replaced.

Circuit breaker

An automatic resetting circuit breaker in the junction block is used to protect the power window system circuit. The circuit breaker can protect the system from a short circuit, or from an overload condition caused by an obstructed or stuck window glass or regulator.

The circuit breaker cannot be repaired and, if faulty, it must be replaced.
