Normal Operation
WARNING: This page is about a different car, the 2008 Mercury Sable, 2008 Ford Taurus X, and 2008 Ford Taurus. 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). The accessory delay relay is integral to the SJB. 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
