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 from the accessory delay relay through circuit CBP47 (GN/BU) and is grounded to chassis through circuit GD133 (BK). When the LH front window control switch is operated in the UP position, the LH front window motor receives power through circuit CPW11 (BU/GY). When the LH front window control switch is operated in the DOWN position, the LH front window motor receives power through circuit CPW10 (YE/VT). When the LH front window motor receives a ground signal on circuit CPW29 (VT/GY), the LH front window motor will enter one-touch up/down mode. The LH window motor receives battery power through circuit SBP01 (RD) at all times, and delayed accessory power through circuit CBP41 (BU) when the key is ON and the delayed accessory feature is active.

This pinpoint test is intended to diagnose the following:

Fuse(s)
Wiring, terminals or connectors
Inoperative LH front window motor
Inoperative LH front window control switch
LH front window motor not initialized
