Master Window Control Switch

The LH (Left Hand) front window control switch is supplied voltage whenever the accessory delay relay is active. For additional information about the accessory delay relay, REFER to Delayed Accessory Power.

Base

- The LH (Left Hand) front window control switch supplies operating voltage to both rear passenger window control switches whenever the lock-out switch is in the UNLOCK position.

- The LH (Left Hand) front window control switch supplies high current voltage and ground directly to the LH (Left Hand) power window motor to move the window upward and downward.

- When operating any passenger power window from the LH (Left Hand) front window control switch, low current voltage signals are sent to the corresponding passenger window control switch to move the window up or down.

- The LH (Left Hand) front window control switch contains integral electronics to control the one-touch down operation of the LH (Left Hand) front power window.

XLT, Limited

- The LH (Left Hand) front window control switch supplies operating voltage to both rear passenger window control switches whenever the lock-out switch is in the UNLOCK position.

- When operating the driver or any passenger power window from the LH (Left Hand) front window control switch, low current voltage signals are sent to the LH (Left Hand) power window motor or corresponding passenger window control switch to move the window up or down.

Passenger Window Control Switch - Front

The RH (Right Hand) front window control switch is supplied voltage whenever the accessory delay relay is active. For additional information about the accessory delay relay, REFER to Delayed Accessory Power.

Base

The RH (Right Hand) window control switch contains 2 relays, which when at rest (inactive), provide a ground path to the power window motor circuit(s).

When the LH (Left Hand) or RH (Right Hand) front window control switch is activated, the corresponding relay located within the RH (Right Hand) window control switch is energized which supplies voltage (high current) to operate the power window motor in the desired direction.

XLT, Limited

The RH (Right Hand) window control switch contains 2 detent positions for each window switch direction. Activating the switch to the first detent position provides a voltage signal (low current circuit) to the corresponding window motor circuit for the direction desired. Activating the switch to the second detent position provides a voltage signal (low current circuit) to both (up and down) window motor circuits to operate in one-touch up/down mode. The RH (Right Hand) power window motor interprets the desired window direction based upon which signal it receives first.

Passenger Window Control Switch - Rear

The rear window control switches receive voltage (high current circuit) from the accessory delay relay whenever it is active. For additional information about the accessory delay relay, REFER to Delayed Accessory Power. The rear window control switches receive voltage (low current circuit) from the LH (Left Hand) front 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 the LH (Left Hand) or 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.

Window Regulator Motor - Front

Base

The front power window 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.

XLT, Limited

The front power window motor contains integral electronics that control and monitor the glass movement (for obstacle detection and one-touch up/down functionality). The front power window motor inputs contain these circuits:

- Battery voltage (high current circuit to operate the motor for glass movement)

- Ignition voltage (low current circuit to power the logic of the integral electronics within the power window motor)

- Ground (circuit provides ground for motor operation as well as logic of the integral electronics within the power window motor)

- Up (low current voltage signal comes from the window control switch when activated to move the glass upward (or anytime the window control switch is placed in the second detent position))

- Down (low current voltage signal comes from the window control switch when activated to move the glass downward (or anytime the window control switch is placed in the second detent position))

Window Regulator Motor - Rear

The rear power window 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.
