Windows and Glass (Without One-Touch Up): Other Ford Escape III

Power Windows

Standard power window features include one-touch down operation (LH front window only) when the master window control switch is momentarily pressed to the second detent and released.

The window control switch

1. may be used to manually raise or lower all windows from the master window control switch or the individual side window from the corresponding door switch.
2. has a rear passenger window lock-out feature.

Rear Window Defrost

The BCM controls the rear window defrost relay (located in the BJB). The BCM activates the rear window defrost relay when the rear window defrost switch is pressed. When the rear window defrost relay is active, the rear window defrost grid is energized.

Delayed Accessory Power

The accessory delay relay, located in the BJB, provides voltage for the operation of the power windows.

The BCM activates the accessory delay relay whenever the ignition is in the RUN or the ACC position, or when the ignition is changed from RUN or ACC to the OFF position and the LH and RH front doors are closed.

The BCM deactivates the accessory delay relay when

1. the LH or RH front door is ajar and the ignition is in the OFF or key-out position.
2. approximately ten minutes have elapsed since the ignition was changed from ACC or RUN to the OFF position.

Rear Passenger Windows Lock-Out

When the lock-out switch (part of the master window control switch) is in the LOCK position, the rear passenger power windows only operate from the master window control switch.

When the rear window defrost switch is activated, the BCM activates the rear window defrost relay (located in the BJB). When the rear window defrost is activated from the switch, the rear window defrost grid is energized and the BCM supplies voltage to illuminate the rear window defrost switch status LED. The rear window defrost system may also be automatically activated as an extra load for accelerated engine warm-up, however the defrost switch status LED remains off unless the defrost switch is activated.

The BCM deactivates the rear window defrost relay when one of these conditions is met

1. The rear window defrost switch is pressed when the feature is active.
2. Ignition state is changed from ON to OFF.
3. A predetermined timer completes.
4. Battery voltage has dropped below a specified threshold (load management strategy).

Master Window Control Switch

The master window control switch is supplied voltage whenever the accessory delay relay is active.

The master window control switch

1. contains integral electronics to control the one-touch down operation of the LH front power window.
2. supplies high current voltage and ground directly to the LH front power window motor to move the window upward and downward.
3. supplies high current ground circuit for all passenger window operation.
4. supplies high current voltage to the rear power windows when the lock-out switch is in the UNLOCK position.

Passenger Window Control Switch - Front

The RH front window control switch receives voltage whenever the ignition relay is active. Ground is provided through the master window control switch.

The RH front window control switch contacts are normally closed. When the RH front window control switch is activated, voltage and ground are supplied to operate the power window motor in the desired direction.

Passenger Window Control Switch - Rear

The rear window control switches receive voltage whenever the rear passenger window lock-out switch (part of the master window control switch) is in the UNLOCK position. Ground is provided to the rear window control switches through the master window control switch.

The rear window control switch contacts are normally closed. When the rear window control switch is activated, voltage and ground are supplied to operate the power window motor in the desired direction.

Window Regulator Motor

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

Window Grid Wire Repair

General Equipment : Polypropylene Film Fine Line Tape (Commercially available)

MATERIAL SPECIFICATIONS

Note. The grid line material is not embedded into the glass, but is baked to the glass surface and consequently can be scraped off. An undamaged grid line will have small ridges that project above the surface of the glass and can easily be felt when running a fingernail across them. Grid lines that have been "razor bladed" will feel smooth when a fingernail is dragged across the affected area. Inoperative lines may appear to the eye to be undamaged due to residue remaining on the glass and will require diagnosis with a voltmeter or 12V test lamp. For additional information, refer to DIAGNOSIS AND TESTING .

1. Bring the vehicle up to a room temperature of at least 16°C (60°F) or above.
2. NOTE: Do not use scrapers, sharp instruments or abrasive window cleaners on the interior surface of the rear window glass as this may cause damage to the grid lines. Clean the entire grid line repair area with glass cleaner and 0000 steel wool to remove all dirt, wax, grease, oil or other foreign material.
3. Mark the location of the grid break on the exterior of the rear window glass.
4. Using a polypropylene film fine line tape, mask the area directly above and below the grid break extending the tape 26 mm (1.02 in) beyond the concern area in both directions. The break area should be at the center of the mask.
5. NOTE: If the brown layer is not broken or missing, apply only the silver grid repair compound to the break. If both the brown and silver layers of the grid are broken or missing, apply a coating of the lacquer touch up paint across the break in the grid line prior to applying the rear window defroster repair compound. Do not overlap the silver grid line with the paint. Several applications may be necessary to achieve a color match. NOTE: Allow at least 5 minutes of drying time between applications for the touch up paint or the silver repair coating. Applying fewer coats or not allowing adequate drying time between coats will produce repaired resistance that is greater than OEM resistance, resulting in poor defrost performance and excessive localized heating. Apply the repair coating to the grid break area in several smooth, continuous strokes. Extend the silver repair coating at least 6.35 mm (0.25 in) on both sides of the break area. Apply a minimum of 6 applications of the grid repair compound.
6. NOTE: The repair coating air-dries in approximately one minute and can be energized after 5 minutes. Optimum adhesion occurs after approximately 24 hours. Allow the repair area to dry completely and remove the mask.
7. NOTE: Be careful not to damage the grid line with the razor blade. If this occurs, additional repair may be necessary. Remove any excess repair compound above or below the grid line with a razor blade.
8. NOTE: The interior side of the grid lines are not painted, but due to the silver tarnishing will tend to change the grid to a gold or brown color. The repair area will be bright silver and will also tarnish over time to match the rest of the grid. Test the system for normal operation.

Lead Terminal Repair

General Equipment : Terminal Kit - Back Glass 4F1Z-14421-AA

1. Bring the vehicle up to room temperature of at least 16°C (60°F) or above.
2. NOTE: The new terminal will cover the original terminal location, but it must be placed so that the terminal conductive areas will be placed on a good conductive base. Clean the bus bar in the area to be repaired with steel wool (000 to 0000 grade), and then with glass cleaner to remove all dirt, wax, grease, oil or other foreign material.
3. NOTE: Do not use any type of flame torch or flame-heated soldering gun for this procedure. Use of these tools provide inadequate heat generation at the tip and the exhaust heat can cause damage to plastic trim parts in the area. Use only an electric soldering gun with 100 watts or more of power. Before using the soldering gun, be sure to melt a small amount of rosin core solder to the tip. The solder will assist in achieving better heat transfer from the soldering gun tip to the new terminal. NOTE: Depending on the original terminal location, and whether the terminal is covered by pillar trim, will determine where to locate the new terminal. Some grid line bus bars may only allow the placement of the terminal above or below the original tab location due to space limitations. For most vehicle applications, the replacement tab location will cover the original tab location, but still allow the replacement tab to attach to the bus bar on good conductive material. Place the replacement terminal type A over the original tab location, making sure the conductive areas of the terminal will be on a good conductive area. Do not place the terminal tab foot on the original location, which does not have conductive material.
4. Hold the terminal in place with an item such as a regular lead pencil at a 90 degree angle from the terminal. (Holding at other than a 90 degree angle may allow the terminal to slip when the solder liquefies.)
5. NOTE: The new terminal has pre-applied solder, flux and temperature-sensitive paint. The paint provides a visual indication when the terminal has reached the correct temperature to melt solder on the terminal. When the correct temperature is achieved, the temperature paint will liquefy and change color. Place the soldering gun tip on the top of the terminal, but not on the painted areas of the tab. Energize the soldering gun and watch for the painted area of the terminal to liquefy and change color. The paint should liquefy in approximately 25-45 seconds after heating. As soon as the paint color completely changes on either side of the terminal, de-energize the soldering gun and continue to hold the terminal in place with the soldering gun and pencil for an additional 30 seconds.
6. Remove the soldering gun and pencil from the terminal. The terminal should be allowed to cool for another 2 minutes before the wiring lead is attached to the terminal.
7. Attach the electrical lead connection to this terminal, turn on the heated rear window and verify the operation.
