2009 Infiniti QX56 AWDFACTORY OEM SERVICE PROCEDURE

Power Window Lock

The power window lock is designed to lock operation of all windows except for front door window LH.

When in the lock position, the power window lock signal is transmitted to power window and door lock/unlock switch RH and rear power window control unit LH/RH by power window serial link. This prevents the power window motor from operating.
