Rear Door Window Operation - SuperCab and SuperCrew

The rear window control switches contain 2 relays, which when at rest (inactive), provide a ground path to their respective power window motor circuit(s). The rear window control switches receive voltage (high current circuit) from the accessory delay relay whenever it is active. The accessory delay relay is integral to the BCM and cannot be serviced separately. When the rear window control switches receive a voltage signal from the driver door window control switch and/or when the rear door window control switch is activated, the rear door window control switch supplies high current voltage (and ground) to operate the power window motor in the desired direction.
