Rear window won t stay up

Rear Passenger Power Window Operation
The rear passenger power window switches receive battery voltage through the window lockout control circuit if the window lockout function is disabled. Ground for the rear passenger power window motors is supplied through normally closed up and down contacts of both the rear passenger power window switches and the driver power window switch. When the either rear passenger power window switch is placed in the down position, the power window motor down control circuit is switched to 12 volts and is applied to the down side of the rear passenger power window motor. Since the other side of the rear passenger power motor is connected to ground through the normally closed up contacts of both the rear passenger and driver power window switches, the window travels down. By placing the rear passenger power window switch in the up position, the polarity of the power window motor is reversed and the window travels up.
The rear passenger power windows can also be controlled from the driver power window switch.

Did you try pushing the lock out switch on the drivers master switch ?

the sunroof needs to be adjusted-lookjust below the glass on the inside on the sides-there should be 4 screws/bolts- loosen the rear ones and pushup then retighten the screws/bolts-cheers Denny

first check fuse if good then check to see if there is power from the window switch. If yes then check window motor it's probley bad.If the motor runs then the regulater is shot.

Door latch on door itself is in closed position if it will not close at all. In this case, open door and pull outside handle hard to pop open door latch. If you have door opening at random, door latch needs replacing or door catch on body is loose.

What worked on my Buick Terraza was: Car parked.Keys in your hand. Put the key in the ignition and turn it one position then press the button of the switch to close the windows (without doing anything else in between).

it may need to be reset.

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.

• The power rear window is inoperative (Explorer Sport Trac only)

• Circuitry.
• Battery Junction Box (BJB) fuse 3 (30A).
• Central Junction Box (CJB) fuse 20 (7.5A).
• Power rear window control switch.
• Rear window glass motor.

• Go To Pinpoint Test K .

------------------------------

There is a micro switch in the latch that seems to fail too often. Does the over-head warning lamp continually flash ? If so, this is an electrical problem.

The side flaps should lower when the top is fully secured in either up or down positions.

The side flap motors seem to be about as durable as the rear side window lift assembly in this vehicle, which is not long. Side rear window lift assemblies are replaced a lot when the vehicle is around 5 to 6 years old..

Due to the complexity of the system and the need for a factory manual or experience to locate all the safety features and switches to this system, you need to consult your dealer.

Yes very typical

most likely the window regulator is bad the buicks have a lot of problems and most of the time it is the cable but you usually have to buy it as a unit with the motor.

The rear windows are controlled by a timer in the top's ECU. If
the rear windows stop fully closing before your top is closed, the
problem MAY be with top's hydraulic system.

Check your top's hydraulic reserve tank for low fluid level. Lack
of fluid will greatly delay the top's closing sequence, leaving
those rear windows partially open.
Your top's hydraulic pump system is located beneath the right side
of the cubby/storage box behind the front seats. Raise the cover
and you'll see a removable trim panel on the right side. The pump
is behind that access panel.

You can use power steering fluid to top off the tank, but don't
fill it above level indicator line. You may have to add more fluid
after you cycle the top up and down to get the air bubbles out of
the lines.
It could also be a relay. On a 95 the relays that are in the trunk above the battery.
Perhaps, just switching the relays might prove which one is failing..
