POWER WINDOW LOCK
With front left and right only power window anti-pinch system
The power window lock is designed to lock operation of all windows except for front door window LH. When in the lock position, ground of the rear LH and rear RH power window switches in the main power window and door lock/unlock switch is disconnected. The power window lock signal is transmitted to front power window switch RH by power window serial link. This prevents the power window motors from operating.
With front and rear power window anti-pinch system
The power window lock is designed to lock operation of all windows except for front door window LH. When in the lock position, ground of the rear LH and rear RH power window switches in the main power window and door lock/unlock switch is disconnected. The power window lock signal is transmitted to front power window switch RH rear LH and rear RH power window switches by power window serial link. This prevents the power window motors from operating.
RETAINED POWER OPERATION
When the ignition switch is turned to the OFF position from ON or START position.
Power is supplied for 45 seconds (with front left and right only power window anti-pinch system )
