Normal Operation
WARNING: This page is about a different car, the 2007 Lincoln MKX and 2007 Ford Edge. 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 delayed accessory relay output from the smart junction box (SJB). The delayed accessory relay is integral to the SJB module. The LH front power window control switch is grounded to the chassis through circuit GD133 (BK).
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- LH front window control switch
- SJB
