WARNING: This page is about a different car, the 2010 Mercury Milan, 2010 Lincoln MKZ, and 2010 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
Under normal operation, the LH front window control switch receives power through circuit CBP47 (GN/BU), which is the accessory delay relay output from the Smart Junction Box (SJB). Ground is provided to the LH front window control switch through circuit GD126 (BK/WH). When the LH front window lockout switch is in the UNLOCK position, power is supplied to all passenger window control switches through circuit CPW14 (VT/WH).
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- LH front window control switch
