Normal Operation
WARNING: This page is about a different car, the 2014 Lincoln MKX and 2014 Ford Edge. 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 RH front window motor and LH and RH front window control switches. The RH front window motor has dedicated high current voltage and ground circuits. When the LH or RH front window control switch is activated, a low current voltage signal is supplied to the RH front window motor which causes the window to move upward or downward. When the LH or RH front window control switch is pressed or pulled to the second detent position (AUTO), the LH/RH front window control switch also provides a ground signal to the RH front window motor to request the one-touch up/down operation.
This pinpoint test is intended to diagnose the following:
- Fuse
- Wiring, terminals or connectors
- Window control switch
- Power window motor
