Window Operation
WARNING: This page is about a different car, the 2007 Mercury Mariner and 2007 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
The smart junction box (SJB) may also be identified as the generic electronic module (GEM).
The window system operates under the control of the accessory delay relay. The SJB will ground the coil side of the accessory delay relay when the ignition switch is in the ON position. When the accessory delay relay is active, power is supplied to each window control switch. The window control switches direct power and ground to the appropriate power window motor.
