How to Replace Rear Auto Glass Yourselfby Bryan Clark
Repairing damaged rear auto glass yourself is significantly cheaper than having the replacement done commercially. Most people replace auto glass when it is cracked or showing signs of wear such as scratches. Usually a car owner hires a professional to install the auto glass to ensure that it has a snug, weatherproof fit. However, recent advances in window design and installation technique have helped make it a do-it-yourself project. If you have basic auto repair knowledge you can perform this installation correctly.
Remove any wires that are connected to your rear window defroster. Remove the window trim and weatherstrip seal. Use a razor blade to remove all of the old adhesive and urethane around the window.
Lift the old window out of its groove. Remove all of the remaining urethane sealant from the groove using a razor blade.
Use a caulk gun to apply a thin line of urethane sealant around the inside edge of the window opening. Apply a thin line of sealant around the edges of the new window.
Set the new window into the groove within the window opening.
Allow the window to set and the urethane to harden. This can take 12 to 24 hours. Clean excess sealant from the glass and replace the window trim.
