POWER WINDOW LOCK
Note. For wiring diagrams, see WIRING DIAGRAMS .
The power window lock prevents operation of all windows except the driver window.
When the lock switch is pressed to lock position, ground of the right front power window switch and the left/right rear power window switches (Crew Cab) are disconnected in the main power window and door lock/unlock switch. This prevents the right front power window motor and the left/right rear power window motors (Crew Cab) from operating.
