Normal Operation
WARNING: This page is about a different car, the 2009 Mercury Milan, 2009 Lincoln MKZ, and 2009 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 CPW30 (GY/YE), which is the accessory delay relay output from the smart junction box (SJB). The accessory delay relay is integral to the SJB module. The LH front power window control switch is grounded to the chassis through circuit CD126 (BK/WH).
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- LH front window control switch
- SJB
