All windshields are formed with two glass panes and a central layer of plastic. They are fixed in place at the windshield frame with urethane adhesive that sticks at room temperature. Since this adhesive is tough to remove, it is usually difficult to restore the windshield which also backs up the roof and holds air bags in place. Before taking off the windshield, see if you can get the necessary moldings from the parts supplier. The Fein Power Cutout Knife and the Equalizer Magnum, Interior Auto Glass Cut Out Knife are the tools I suggest. Should the windshield crack, the exterior can be cut using a cold knife; however, when salvaging is needed, use a power reciprocating or oscillating knife from the inside. Removal of the windshield is done by removing the rear view mirror, windshield
Wiper Arms, cowl cover and the A-pillar trim on the attached urethane adhesive which is then cut with a sharp cold knife or power device. While you are installing the door, open the door's left front glass to ensure no air builds up inside and keep the urethane sealed in for at least 24 hours. Ensure there are support spacers and squeak tape, use an ammonia-based cleaner on the windshield, cover it with Glass Prep and Glass Primer and slide it into the opening, ensuring everything fits smoothly. Once the urethane is cleaned, apply tape if that's what you did before and, once it has cured, test the repair with water. Only then should you reinstall the cowl covers and rear view mirror.
