I just changed the right rear power window motor and regulator because it didn't go up or down. After putting everything back together with the new motor and regulator I turned on the car and hit the switch. The window went up and when i tried to make it go down it would not. I tried from both the main switch and fro the rear window switch. What could be wrong and where should I look? All of the other windows and locks are working. Please help

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 .

well if you have power for up and down at the plug then it isnt a relay or fuse issue or you would have no power, did you just replace the motor only? it might be the regulator also, if it went down and wouldnt go back up then thats probably the issue a failed window regulator and thats the assembly that attaches the window to the motor and allows the motor to move the window

Im not 100% sure about the rear but with the front windows i removed the panel then the foam piece. I then removed the torx screws holding the regulator from the motor itself there were three in the front windows not sure about the back. There were 4 rivits holding the regulator to the door which i had to drill out. Once i put the new regulator in i put new rivits in attatched the window to the regulator via the blue clips and put it all back together.

regulator usually wears out and breaks or gets bound and burns up motor, change them both if available. Good sign of bad regulator is sloppy window in track, or window off track. I always replace them together if they are available. it is possible that you just need a switch, but most likely the reg/motor.

Here's a video that will show you how to replace the rear window regulator in that car.
">

To remove the window motor on this truck remove the door panel to access the window regulator and motor assembly. The regulator might be riveted in so you will have to knock out the rivets to remove it and replace them with bolts and nuts. Once you remove the rivets lower the regulator and window down to slide regulator out of the channel on the bottom of the window once removed from window push window back up and tape in position to pull regulator and motor out unbolt motor of regulator being careful not to let tension spring on regulator to release real fast it will mess it up. Replace motor and reinstall regulator assembly back in the door on the window and bolt into place. Put door back together.

its the window regulator. not to bad to change. just a couple of screws to remove the door panel. peel the liner back & remove the 6 10mm bolts and uunhook the electrical connector and the window from the regulator. installation is reverse

be sure motor is problem and not regulator ..look for worn teeth on regulator..motor comes away with 3 bolts and simply change out with new motor..regulator with motor change out is more nasty ..bolts need to replace rivets you will be cutting away

I had the same problem with the driver's side front and rear windows. Had to replace the motor assemblies.
