Power Window Operation
WARNING: This page is about a different car, the 2002 Ford Ranger. However, it is still accessible from the selected car via links, so may be relevant.
The power window system operates under the control of the window safety relay. The window safety relay receives fused ignition voltage when the key is in RUN or ACCESSORY. The window safety relay when energized supplies power to the one touch-down (OTD) relay and the master power window switch.
