Component Description

WARNING: This page is about a different car, the 2015 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.

Master Window Control Switch

The master window control switch receives voltage whenever the delayed accessory relay is active. The master window control switch is grounded through the DDM. The master window control switch communicates to the DDM through a LIN.

For SuperCab and SuperCrew, the master window control switch supplies low current voltage signal through momentary contacts to activate the internal relays within each of the rear passenger window control switches to operate the rear windows.

Passenger Door Window Control Switch

The passenger door window control switch contains momentary contacts (one for each window switch direction). The PDM provides a return (ground) for the passenger door window control switch. When the control switch is activated, a ground signal is supplied to the PDM to operate the passenger door window regulator motor in the desired direction.

Rear Door Window Control Switch - SuperCab and SuperCrew

The rear window control switches receive voltage (high current circuit) from the delayed accessory relay whenever it is active. The rear window control switches receive voltage (low current circuit) from the master window control switch when the lock-out switch is in the UNLOCK position. The rear window control switches each have a dedicated ground circuit. 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).

When a rear window control switch is activated, the corresponding relay located within the rear window control switch is energized which supplies voltage (high current) to operate the power window motor in the desired direction.

Front Door Window Regulator Motor

The door window regulator motor(s) are bi-directional. Window direction is determined by the polarity of the voltage being supplied to the motor from the associated door module. The door window regulator motor contains 2 Hall-effect sensors. The Hall-effect sensor power supply and return circuits are provided by the associated door module.

Rear Door Window Regulator Motor - SuperCab and SuperCrew

The rear door window regulator motors are bi-directional. Window direction is determined by the polarity of the voltage and ground being supplied to the motor from the window control switch.

Front Controls Interface Module (FCIM)

The FCIM contains the rear window defrost button and also controls the rear window defrost relay.

Front Display Interface Module (FDIM)

The FDIM contains a redundant rear window defrost button on the touchscreen display. The FDIM plugs directly into the APIM, and does not communicate directly on any network.

Driver Door Module (DDM)

The DDM receives power window commands from the master window control switch through a LIN. The DDM supplies voltage and ground to operate the driver door window regulator motor.

The DDM also communicates master window control switch requests to the PDM through the Medium Speed Controller Area Network (MS-CAN) to operate the passenger door window regulator motor.

Passenger Door Module (PDM)

The PDM receives power window commands from the passenger door window control switch or from the DDM through the Medium Speed Controller Area Network (MS-CAN). The PDM supplies voltage and ground to operate the passenger door window regulator motor.

Power Sliding Rear Window Motor

The power sliding rear window motor is bi-directional. Window direction is determined by the polarity of the voltage being supplied to the motor. When the power sliding window switch is activated, voltage is supplied to activate either the power sliding window open relay or the power sliding window close relay (both relays are located in the BJB). When the power sliding window open (or close) relay is active, voltage is supplied to one side of the power sliding window motor while ground is supplied through the normally closed relay contacts of the opposing/inactive power sliding window open (or close) relay.
