Fixed Backlight
WARNING: This page is about a different car, the 2007 Lincoln MKX and 2007 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
For Edge, when the accessory delay relay is energized, switched voltage is supplied to the window control and door lock switches. The memory set switch is powered through the drivers seat module (DSM).
The MKX is not equipped with any fixed backlight components.
