Learning how to replace a windshield in a Chevy Blazer can come in handy if your insurance company does not cover the charge and you'd like to save some money. The task is not overly difficult, but does take a bit of time, and having a second person to assist is highly recommended. To improve the look of your truck or prevent the windshield from cracking later on, read on to learn how to replace a windshield on a Chevy Blazer.
- A new windshield
- A flat-head screwdriver
- A utility knife or razor blade
- A gasket scraper
- A crowbar
- Windshield bonding agent
- Silicone caulk and a caulking gun
- Purchase a replacement windshield for your Chevy Blazer. Used windshields can be purchased from local auto salvage yards. Be sure to purchase one for the same year as your Blazer. Windshields are the same for all Chevy Blazer models each year, including the S10, full-size and Jimmy models, and are interchangeable between the models for that year.
- Remove the windshield wiper arms. Lift the wiper arms up and away from the windshield. Use the flat-head screwdriver to press the tab holding the wiper arm in place. Lift up to remove the wiper arms. Set aside.
- Scrape off the weatherstripping from the old windshield. Use the screwdriver to pry the weatherstripping from the old windshield, taking care not to scratch the truck body. Work all the way around the windshield to remove as much of the weatherstripping as possible.
- Cut the old windshield from the Chevy Blazer. Use the utility knife or razor blade and gasket scraper to carefully slice through the remaining adhesive all the way around the old windshield.
- Remove the old windshield. Using the crowbar and a second person if available, gently pry the old windshield from the Blazer and carefully set it aside. Use the gasket scraper and sandpaper to remove any remaining adhesive from the area. Clean the area, removing any dirt or debris. Having a fresh surface to work with before attempting to install a new windshield on your Chevy Blazer is crucial for obtaining a good seal.
- Apply the bonding agent. Squeeze a thin bead of the windshield bonding agent to both the Chevy Blazer frame and the windshield, applying the bonding agent to where the two pieces will meet.
- Apply the silicone caulk to the Chevy Blazer frame. Using the silicone caulk and the caulking gun, run a uniform bead of the caulk around the Chevy Blazer's windshield frame in the same area where you applied the bonding agent.
- Install the new windshield. Using the help of a second person, carefully install the new windshield. Press the windshield into place and check the installation for proper placement as well as a good seal with the silicone caulk. If any area is lacking in silicone caulk, remove the windshield and add more caulk. A good seal is essential to prevent wind noise and water leakage. Use the gasket scraper to carefully remove any excess caulk that may have been squeezed out.
- Install the weatherstripping and windshield wiper arms. Press the weatherstripping into place, working all the way around the new windshield. Re-install the windshield wiper arms. Allow the Chevy Blazer and new windshield to sit for at least 24 hours before driving, preferably in a dry area like a garage, to allow the seal to cure.
