Ranger Glass Components, Part 1:

Ranger Glass Components, Part 2:

Quarter Glass
The quarter glass is standard on Super Cab Vehicles. The quarter glass is available either as a fixed or as a flip window. The fixed quarter glass is bonded to the opening flange with urethane adhesive and nuts.

Back Window Glass
The back window glass is standard plastic and glass laminate safety glass. The back window glass may be split with a sliding window or a one piece window.

Windshield Glass
The windshield glass is standard plastic and glass laminate safety glass. The windshield glass is bonded to the window opening flange with urethane adhesive.

Front Door Glass
The front door glass is standard plastic and laminate safety glass. The front door glass is lowered and raised manually or with the optional power window controls.

FOUR-DOOR, SUPERCAB

Quarter Glass
The quarter glass is standard on Super Cab vehicles. The quarter glass is available as a fixed window that is bonded to the opening flange with urethane adhesive and nuts.

PRINCIPLES OF OPERATION

Power Window Operation
The power window system receives power from the accessory delay relay. The accessory delay relay receives fused ignition voltage when the key is in either the RUN or ACCESSORY position. When the accessory delay relay is energized, it supplies power to the one touch-down (OTD) relay and the master power window control switch.

Power Window Control
The power windows can be operated from the individual window switch located on each door panel. The passenger power window can be operated from the driver (master) power window switch. The driver side window has two modes of operation: manual and auto. In manual mode, the window control switch will move the window down until the switch is released.

Auto mode provides one-touch down (OTD) operation for the driver window only. The OTD function moves the driver window to the full open position when the master power window switch is momentarily pressed and released.

One Touch Down Relay
The one touch down relay, which is located in the smart junction box (SJB), receives voltage from the accessory delay relay when the key is turned to either the RUN or ACC position. Voltage to the accessory delay relay is supplied on pin 5, and pin 1, circuit 400.

The one touch down relay is controlled by the SJB, and will only operate when the ignition is in either the RUN or ACC position. A one touch down request is initiated when the master window control switch is pressed down for approximately 62 to 320 ms. When the SJB senses a one touch down request, it will ground the OTD relay coil through pin 2. The OTD relay provides power to the LH front power window motor on pin 4, circuit 991, and moves the window to the full open position until one of the following conditions is met:
- Seven seconds have elapsed.
- The window glass reaches the bottom of the track, and window motor stall is detected by the SJB.
- The master window control switch is pressed up or down.

The one touch down feature has five inputs and one output. The inputs are:
- Ignition switch position.
- One Touch Down Sense High Input.
- One Touch Down Sense Low Input.
- Down Window Command Input.
- Up Window Command Input.

The outputs are:
- One Touch Down Relay Output.

Smart Junction Box
In addition to being an electrical distribution center for several vehicle systems, the smart junction box (SJB) is a multi-function electronic module, with inputs and outputs for several electrical systems, including the power window system.

During normal operation, the SJB constantly monitors the circuits of electronic systems it controls. If the SJB detects an open, a short to ground, or a short to power in the driver side power window circuits, it will set a diagnostic trouble code (DTC). DTCs can be retrieved with a diagnostic tool. SJB DTCs related to the power window system will not illuminate the malfunction indicator light.
