If your windows are starting to make funny noises when you put them up or down, are binding or not running smoothly all the way through the range of motion there is a good chance your window regulators are starting to fail. It is a good idea to replace the regulator before it fails completely because there is no way to get the window back up into the closed position once it fails short of replacing the regulator.

To begin you will need to remove the door panel. Please see our article on removing your front door panel and complete the work there before starting this project.

You will need to remove the door panel to change the window regulator.
Figure 1

You will need to remove the door panel to change the window regulator. Start with the car on level ground and the window all the way up.

Tape or wedge the window securely in the up position.
Figure 2

Tape or wedge the window securely in the up position. Once you remove the regulator the window will fall and can easily break if it is not held in the up position (red arrow).

Disconnect the wiring to the regulator motor by pulling it straight off (red arrow).

Use a 10mm socket and remove the five bolts holding the regulator and motor in place (red arrows).
Figure 4

Use a 10mm socket and remove the five bolts holding the regulator and motor in place (red arrows). Use care as once you remove the last bolt the regulator is free from the door.

There are two small wheels on the end of the regulator.
Figure 5

There are two small wheels on the end of the regulator. The upper wheel (red arrow) rides in the lower window channel and you slide the regulator forward to remove it from the channel. The lower wheel (yellow arrow) rides in a channel mounted in the door and you slide the regulator toward the back of the door to remove it.

With the guide wheels out of the channels you can carefully wiggle the regulator out form the opening in the lower door.
Figure 6

With the guide wheels out of the channels you can carefully wiggle the regulator out form the opening in the lower door. It is easier to move the motor forward and up and then remove the regulator arms first. Installation is the reverse of removal. Make sure to test the regulator before you put the door panel back on.
