Normal Operation
WARNING: This page is about a different car, the 2011 Mercury Milan, 2011 Lincoln MKZ, and 2011 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
Under normal operation, the accessory delay relay supplies voltage to the master window control switch and the RH front window control switch. The RH front power window motor has dedicated high current power and ground circuits. When the master window control switch or RH front window control switch is activated, a low current voltage signal is supplied to the RH front power window motor which causes the window to move upward or downward.
This pinpoint test is intended to diagnose the following:
- Fuse(s)
- Wiring, terminals or connectors
- Power window motor
- Window control switch
