WARNING: This page is about a different car, the 2004 Mercury Monterey and 2004 Ford Freestar. However, it is still accessible from the selected car via links, so may be relevant.
The LH window control switch can be used to power either the LH window or the RH window. A single window control switch is located on the passenger door armrests to activate the passenger window only. The LH window control switch supplies voltage and a ground to the window motors for operation of the front window motors in the commanded direction.
