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). This is the only shared circuit between all front and rear power windows.
This pinpoint test is intended to diagnose the following:
- Accessory delay relay
- Circuit breaker
- Wiring, terminals or connectors
- LH front window control switch
