Passenger Door Window Control Switch
WARNING: This page is about a different car, the 2018 Ford EcoSport. However, it is still accessible from the selected car via links, so may be relevant.
The passenger door window control switch receives voltage (high current circuit) from the delayed accessory relay whenever it is active. The passenger door window control switch contacts are normally closed. The passenger door window control switch has a dedicated ground circuit. The passenger door window control switch contains relays, which when at rest (inactive), provide a ground path to their respective door window motor circuit(s).
When the passenger door window control switch is activated, the corresponding relay located within the rear door window control switch is energized which supplies voltage (high current) to operate the door window motor in the desired direction.
