With Front Power Window Anti-pinch System
WARNING: This page is about a different car, the 2005 Infiniti FX45 and 2005 Infiniti FX35. However, it is still accessible from the selected car via links, so may be relevant.
The power window lock is designed to lock operation of all windows except for driver side door window.
When the lock position, ground of the rear power window switches in the power window main switch is disconnected. The power window lock signal is transmitted to front power window switch (passenger side) by power window serial link. This prevents the power window motors from operating.
