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.

The LH front power window control switch receives power from the accessory delay relay through circuit CPB02 (GN) and is grounded through circuit GD126 (BK/WH). When the LH front window control switch is pressed to the UP position, the LH front motor receives power through circuit CPW11 (BU/GY). When the LH front window control switch is pressed to the DOWN position, the LH front motor receives power through circuit CPW10 (YE/VT). When the LF window motor receives a ground signal on circuit CPW29 (VT/GY), the LF window motor will enter one-touch up or one-touch down.

The RH front power window control switch receives power from the accessory delay relay through circuit CPB02 (GN) and is grounded through circuit GD126 (BK/WH). When the RH front window control switch is pressed to the UP position, the RH front motor receives power through circuit CPW13 (BN/YE). When the RH front window control switch is pressed to the DOWN position, the RH front motor receives power through circuit CPW12 (GN/OG). When the RH window motor receives a ground signal on circuit CPW31 (GN/WH), the RH window motor will enter one-touch up or one-touch down.

This pinpoint test is intended to diagnose the following:

B(+) power lost during LH or RH front window operation
LH or RH front window motor
LH or RH front window control switch
LH or RH front motor not initialized
Wiring, terminals or connectors
