Rear Window Glass won't Release

Does it have gas struts like this? If it clicks, you know the solenoid is working.

The easy way to open the glass without tearing up the tailgate panel or ripping out your carpet:

Pull back the interior tailgate panel right above the bump in the middle where the latch is. There are no screws or bolts in that area, so it should pull away about 2 inches. Then you'll have to reach in and push down the release bar. You should be able to feel for the part that needs to be pushed down to release the glass. Now that it is unlocked, you will be able to open the hatch and the tailgate. Once open, remove the interior tailgate panel, which has one screw on each side.

The failed actuator that needs to be replaced is not all that expensive and can be found at the dealer.

This may be as simple as relearning the window stop positions. Perform the following procedure to relearn the windows;

1) Sit in the drivers seat and ensure both doors are fully closed.
2) Turn the key to the ON position but do not start the vehicle.
3) Pull up on the drivers window switch until the window reaches the full up position, then CONTINUE HOLDING THE SWITCH UP for 2-5 seconds, then release the switch.
4) Push down on the drivers window switch until the window fully opens, then CONTINUE HOLDING THE SWITCH DOWN for 2-5 seconds, then release the switch.
5) Repeat steps 1-4 for the passenger window.
6) Close both windows and check the operation of the smart glass.

SECTION 501-11: Glass, Frames and Mechanisms 2001 Explorer Sport/Sport-Trac Workshop Manual
GENERAL PROCEDURES Rear Window Motor Initialization CAUTION: Make sure that no obstructions are present in the power rear window system when carrying out this procedure.
NOTE: This procedure must be carried out when repairs are performed on any part of the power rear window system including when: the power rear window motor is removed from the window regulator drum housing, a new power rear motor is installed, a new power rear window regulator is installed, a new power rear window module is installed, and any operation in which grease or lubricants are applied to the power rear window system.
NOTE: All power rear window components (window glass module, window regulator, window motor, and glass runs) must be installed and torqued to specification before carrying out this procedure.
NOTE: Steps 1-6 must be completed within 30 seconds. The entire procedure must be completed within five minutes.
NOTE: Once the ignition key is turned to the ON position in Step 6, it must remain on until the entire procedure is completed.
NOTE: Steps 7 and 9 require that the power rear window control switch be held in the closed position until the power rear window motor stalls the window in the upper header seal. Step 8 requires that the window control switch be momentarily turned to the open position.

1. Start with the ignition in the OFF position.

1. Turn the ignition to the ON position.

1. Press the power rear window control switch vent button six times.

1. Turn the ignition to the OFF position.

1. Press the power rear window control switch vent button six times.

1. Turn the ignition to the ON position. The power rear window will move up-down-up-down approximately 20 mm (0.8 in). This movement indicates that the power rear window motor has entered initialized mode.

1. Rotate and hold the power rear window control switch to the closed position until the window stalls in the upper header seal.

1. Momentarily rotate the power rear window control switch to the open position and release. The power rear window will carry out a one-touch down operation until the window stalls at the bottom of the travel stop designed into the window regulator.

1. Rotate and hold the power rear window control switch to the closed position until the window stalls into the upper header seal. Once this operation is complete, the window will move up-down-up-down approximately 20 mm (0.8 in). This movement indicates that the power rear window motor has been successfully initialized.

1. Verify correct operation of the power rear window by moving the window to the fully open, vent, then fully closed positions.

There are some mechanical rods in the rear hatch that are probably rusty and you will have to take the inner panel off to acces and clean them to get them moving to operate the lock.

1st you need to get the window down are all fuses good ....if so you can get the inside panel off and gain access to the motor is the motor bad well you'll need to use a test light and determine power to it with a good ground and test with the key in the on position if power is present then make sure the connection is solid and work the window button if the trunk itself is not fully closed the window switch may not work as well after all above is checked remove the bolts from either the window itself 10 mm i believe or 7/16 wrench to remove the glass then you may open the lid and repair as needed and reassemble the glass close the lock_s itself and use teh switch to drop window down and then pull on the release handle to open the locks back up n close lid hatch and ensure the proper working of the window you may need to adjust the window one way or the other for alignment and if working good at this point reinstall the rear panel and yer done

There is a small plunger on the tailgate, see if that is still doing it's job to push the glass out abit. the other thing too is if the two pistons that hold the glass up is weak can do that and if the car has been out in the sun for a while, i find that the weather strip hold the glass down. Good luck and let me know how your did. 

Followed owners manual for emergency opening of rear window glass.
Removed upholstery panel from the tailgate once glass was opened. Found a broke (plastic) actuator arm on the actuating motor.
Ordered new one for replacement.
