Master 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 master window control switch and the driver front window motor each contain integral electronics which must be initialized whenever:
- a new master window control switch is installed.
- a new driver door window regulator and motor is installed.
- a new driver door window glass is installed.
- carrying out any operation in which grease or lubricants are applied to the driver door window system.
- battery voltage has been removed from the master window control switch for more than 3 minutes (for example, battery or window control switch disconnected).
Refer to: Power Door Window Initialization .
The master window control switch:
- is supplied voltage when the ignition is on or the accessory delay feature is active.
- contains integral electronics to control the one-touch up/down operation of the driver door window.
- supplies high current voltage and ground directly to the driver front power window motor to move the window upward and downward.
- supplies low current voltage to the rear power windows when the lock-out switch is in the UNLOCK position.
