How to Install an Auto Glass Door

The windows in a car have two main components. Naturally, there is the glass itself. But the glass is only held in place by a regulator, responsible for controlling the window as it is rolled up and down. Should you find that you need to install a window into a car door, you'll need to get inside the door. To begin, you'll need to determine the size glass and regulator for your car then remove the door's inner trim panel to install the window. The items you'll need can be purchased at auto body stores and hardware stores.

Instructions

1

Use your car's window controls to roll it all the way down. Once this is done, be sure to disconnect the negative cable on the car battery. Next, open the car door. Remove any weather-stripping from the vehicle's door window by grabbing it near the outer edge of the door.

2

Remove the door handle bezel and window crank from the door. Unscrew and remove the screws attaching the handle bezel by prying it off with a screwdriver. If your vehicle has a manual window crank, dislodge the crank's retaining clip by positioning a rag behind it.

3

Remove all retaining screws on the door's trim panel, keeping in mind that some may be underneath small plastic panels or underneath the area where the handle formerly was. Lift the panel upward, releasing it from any remaining retaining clips. Next, pull it away from the door and make certain to unplug all electrical connectors attached to it. Finally, peel away the water shield.

4

Unscrew the door speakers, pull the speaker out and unplug the wiring behind it.

5

Install the regulator by first folding the sides together, threading it up through the door, unfolding it and then twisting and locking it into place. If the regulator needs to have a motor installed, jiggle the motor onto the cable housing before putting the fastener on and tightening all bolts. Then make sure you've bolted the regulator in place on the door.

6

Hold the window glass above the window opening and slip it down into the door. If possible, you may instead opt to push the glass from the bottom before pushing it back down within the regulator. You'll need then to bolt the glass into place within the window regulator.

7

Reconstruct the door by reconnecting the speakers, then water shield, trim panel, handle, window crank and finally, the weather strip. Now you're ready to test the window by using the car's window controls.
