I left my car with the rear window down in the rain. Should I buy a new window motor and regulator or can I buy just the motor?

There can be several reasons. When you say you "fixed" the windows, it makes me wonder what was wrong with them before you started. The part inside the door is usually a window regulator. It has teeth to be moved by the gear on the electric window motor. The position of the regulator teeth is suppose to match the position of the window. If you imagine setting the window 1/2 open, then that is as far as the window will rise when the electric window motor cranks. The electric motor gear will only travel so many turns for each cycle of the motor switch.


Mixing motors on the wrong side of the car is something else that can go wrong if you change W motors. The W motors are not the same from front to front or rear to rear. They are often compatible diagonally (right front to left rear) (left front to right rear).


Finally, you can have a switch box for the auto up/auto down feature inside the door panels. You need to check for power at the W motor and then backtrack.

You have a defective power window motor and regulator assembly. The regulator is pop riveted in so you must drive out the rivet center and then using a special rivet cutter bit cut the head off the rivets. You can use machine screws to put the new regulator in as long as they are short and don't interfere with the operation of the new regulator. I do not show the rear window regulator as being available in the aftermarket, you may have to buy it from Ford.

GM rear window regulators have a cable which breaks causing this problem. get yourself a new regulator at a parts store and have a glass shop install it for you.

those things last about 10 years, and the most used window generally dies first, go figure. Find and buy a new window regulator on eBay or at a parts store. If you can not find one you will have have to pay through the nose at a dealer parts department. Do not just buy a lift motor, you want an entire new regulator which includes a motor.

Take the car and the new regulator to a glass shop which does auto glass. For about 50 bucks they will put it in for you. That is a bargain.

The window regulator is bad. The cable is probably snapped and allowing the motor to spin freely without moving the glass up or down. Have the regulator replaced.

• 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.

NOTE: The power rear window motor is not on the multiplex link. Any diagnosis and testing carried out on the power rear window will not involve the GEM module. NOTE: The reinitialization 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.

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 master switch on the left front door hold the keys to all. supply your own power the the switch with like a battery from a power drill to see if its the switch in the master assembly.

U will need to buy and replace the window regulator, it is a dealer only part.

1. Raise and support the rear door window glass to the full up position.
2. Remove the interior door handle.
3. Remove the rear door speaker.
4. Remove the water shield.
5. Disconnect the rear door window regulator motor electrical connector.
6. Remove the rear door window regulator rivets.
7. Remove the rear door window regulator by sliding the regulator arms off of the window glass track.
8. Installation is the reverse of the removal procedure, noting the following:
   • Cycle the door glass to make sure of engagement of the drive mechanism.
   • Remove the rear door window glass-to-regulator bolt or rivet.
   • Position the rear door window glass as necessary to access the rear door window glass-to-regulator rivet.
   • Secure the rear door window glass in the full UP position with tape.
   • Disconnect the window regulator motor electrical connector.
   • Remove the 2 window regulator nuts.
   • Remove the 3 window regulator motor bracket nuts.
   • Install the window regulator assembly. Tighten the 3 motor bracket nuts to 89 inch lbs. (10 Nm).
   • Install the 2 window regulator nuts. Tighten the nuts to 89 inch lbs. (10 Nm).
   • Connect the window regulator motor electrical connector.
   • Remove the tape securing the rear door window glass in the full UP position.
   • Position the rear door window glass as necessary to access the rear door window glass-to-regulator rivet. Tighten the bolt to 62 inch lbs. (7 Nm), or install a new rivet.
   • Install the window regulator motor
   • Remove the window regulator assembly.

Remove the window regulator motor

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