System Operation

Power Window Operation - Front

The LH (Left Hand) front power window is equipped with a one-touch down feature (controlled by the master window control switch integral electronics). This allows the LH (Left Hand) front power window to be completely lowered when the master window control switch is pressed to the second detent position and then released.

Passenger Windows Lock-Out

When the lock-out switch (part of the master window control switch) is in the LOCK position, the rear passenger power windows only operate from the master window control switch.

Rear Window Defrost

When the rear window defrost switch is activated, the BCM (Body Control Module) activates the rear window defrost relay (located in the BJB (Battery Junction Box)). When the rear window defrost is actived from the switch, the rear window defrost grid is energized and the BCM (Body Control Module) supplies voltage to illuminate the rear window defrost switch status LED (Light-emitting Diode). The rear window defrost system may also be automatically activated as an extra load for accelerated engine warm-up, however the defrost switch status LED (Light-emitting Diode) will remain off unless the defrost switch is activated.

The BCM (Body Control Module) deactivates the rear window defrost relay when one of these conditions is met:
- The rear window defrost switch is pressed when the feature is active.
- Ignition state is changed from ON to OFF.
- A predetermined timer completes.
- Battery voltage has dropped below a specified threshold (load management strategy).
