Solution

1. Preparation

Tools Required: Safety glasses, gloves, flathead screwdriver, and a plastic scraper.
Ensure the vehicle is parked in a shaded area to prevent adhesive from curing too quickly.
Gather replacement windshield and necessary adhesive if replacement is required.

2. Remove the Damaged Windshield (if replacement is needed)

Disconnect the battery to ensure no electrical issues during the process.
Remove any trim pieces around the windshield using a flathead screwdriver.
Carefully cut the urethane seal around the windshield using a windshield removal tool or a utility knife.
Lift the windshield out carefully to avoid damaging the vehicle’s body.

3. Clean and Prepare the Frame

Remove any existing adhesive from the frame using a plastic scraper.
Clean the frame thoroughly with glass cleaner and a lint-free cloth to ensure proper adhesion of the new windshield.
Allow the area to dry completely.

4. Install the New Windshield

Apply a bead of urethane adhesive around the frame where the windshield will sit.
Carefully place the new windshield onto the adhesive, ensuring it is aligned correctly.
Press down firmly to ensure a proper seal, and avoid moving the windshield once in place.

5. Reassemble and Finish

Reinstall any trim pieces that were removed.
Allow the adhesive to cure according to manufacturer specifications (usually 24 hours).
Reconnect the battery.
