Factory Control Modules (Description)
Some windows use either a central control module, or control modules in each door. These systems
are less common than direct wired systems. These can be found in many newer Volkswagens,
BMWs, Isuzus, Maximas, Grand Cherokees, and many Ford vehicles. If the vehicle has one of
these systems, the 535T must be interfaced between the window switch and the window motor,
effectively eliminating the factory window control module. This often requires the wires to be run
into each door. The 535T monitors the AC “noise” generated by the motion of the motor. For this
reason the 535T cannot drive relays or control modules in the system.
