1. Gather the necessary tools and replacement tempered glass. Make sure you have safety goggles, a pry tool, a glass cutter, silicone adhesive/sealant, a utility knife, and a soft cloth.
2. Roll up the passenger window as high as it can go.
3. Open the passenger door and remove the inner door panel. You may need a screwdriver or panel removal tool to pry off the plastic clips or screws holding it in place. Set the panel aside carefully to avoid damaging it.
4. Lower the power-operated window completely by holding the switch until the glass reaches the lowest point.
5. Disconnect the power cable or wiring clips connected to the window motor or regulator assembly and remove the glass guide/channel if it's holding the glass in place.
6. Place a piece of cardboard and blanket on the ground below to catch the glass fragments safely.
7. Score along the edges of the glass with the glass cutter. Be sure to use safety goggles and make sure the blade is sharp. You may need to cut in several passes to fully sever the glass.
8. Wear safety goggles and carefully tap the glass with a pry tool or hammer tap at the scored area. Tap until the glass breaks along the scored lines.
9. Remove the broken glass pieces and ensure you have picked up all the small pieces to prevent injuries. Clean up any glass shards using the soft cloth.
10. Apply a thin bead of silicone adhesive/sealant around the edges of the new tempered glass. Make sure it's a continuous bead to ensure a water-tight seal.
11. Carefully lower the replacement glass into the window frame. Make sure it sits evenly and is not tilted.
12. Reattach the glass guide/channel to hold the glass in place if necessary.
13. Reconnect the power cable to the window motor or regulator assembly.
14. Raise the power-operated window to its highest position and check that it operates smoothly and lines up correctly.
15. Replace the inner door panel back onto the door. Make sure all clips or screws are properly secured.
Remember to dispose of the broken glass pieces properly and follow any safety guidelines when handling glass. If you're not comfortable performing this task yourself, it's best to consult a professional technician for assistance.
