If you need to replace the windshield glass in your vehicle, this will take at least two people. Also, the exact shape and size of the glass you need will vary, and some precise steps in the replacement procedure can also differ. Check with an auto-glass expert for details on your particular model.
Removal
If youre replacing the front windshield, you need to remove the rearview mirror from inside the car and the wipers from the outside; some rear windshields also have a wiper that needs removing. All these items are usually screwed on, and youll need to rock the wipers to loosen them after removing the screws. If the windshield has a trim panel around it, remove its screws and then use a trim-removal tool, which slips under the trim to catch and remove the clips. If the rubber gasket around the glass is in good condition, just break the seal around it by running a large stick across it. If this gasket is dry or cracked, however, you dont need to save it and must replace it. Cut through the gasket with a knife by inserting it down the middle and running it across the edge of the glass; you need to be careful that you dont actually hit the glass. Now you need to have you assistant sit on the hood or trunk while you enter the car. From within the car, use your foot and the large stick to push out the glass without kicking it. Your assistant needs to be ready to catch the glass. If you cut the gasket, youll need to remove the outer part from the frame; if its intact and in good condition, pull it off of the glass for use with the new glass.
Installation
The windshield frame needs to be clean of rust, corrosion and other debris before installing the new glass. Leaving a new gasket in the sun or a warm room so it will soften. When attaching the gasket to the glass, its thick end goes on the inside along the glass edge. The groove on the outer side should be coated with petroleum jelly; then wrap a nylon cord around that groove so both ends of the cord meet at the bottom center of the gasket and stick out another 2 feet. As your assistant lays the glass on the frame from outside, you can pull the ends of the cord into the interior. You need to pull on one of these ends while the other person pushes on the glass to slip the gasket into position. Before you reconnect the trim, mirror and wipers, it will help to wipe away any excess petroleum jelly.
