Normal Operation
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 power window control switch receives power through circuit CBP47 (GN/BU), which is the accessory delay relay output from the Smart Junction Box (SJB). When the LH front window lockout control switch is in the UNLOCK position, voltage is supplied to the LH and RH rear power window control switches through circuit CPW14 (VT/WH). Ground is supplied to the LH front window control switch through circuit GD126 (BK/WH).
This pinpoint test is intended to diagnose the following:
- Circuit breaker
- Wiring, terminals or connectors
- LH front window control switch
