Step-by-Step Replacement

Step 1: Open the Falcon Wing Door Fully

1. Park in a location with plenty of overhead clearance
2. Open the falcon wing door completely
3. If the window damage prevents normal operation, use the manual release

Step 2: Remove Interior Trim

1. Locate the interior trim panel along the top edge of the door
2. Use plastic pry tools to carefully release the clips
3. Work slowly to avoid breaking the clips
4. Set the trim panel aside safely

Step 3: Disconnect Any Wiring (If Applicable)

Some Model X years have:

• Rain sensors
• Defrost elements
• Antenna wiring

If your window has any electrical connections:

1. Photograph the connector before unplugging
2. Press the release tab and gently disconnect
3. Note which connector goes where

Step 4: Remove the Window Mounting Bolts

1. Locate the Torx bolts securing the window frame (typically T30)
2. There are usually 4-6 bolts along the frame
3. Support the window while removing the final bolts
4. Carefully lift out the damaged window assembly

Step 5: Clean the Mounting Area

1. Remove any broken glass carefully (wear gloves)
2. Clean the mounting surface with a microfiber cloth
3. Inspect the seals and weatherstripping
4. Replace seals if damaged (order separately if needed)

Step 6: Install the Replacement Window

1. Test-fit the new window before final installation
2. Align the mounting holes
3. Hand-thread all bolts first to ensure proper alignment
4. Tighten bolts in a star pattern to ensure even pressure
5. Reconnect any electrical connectors

Step 7: Reinstall Interior Trim

1. Align the trim panel clips with their holes
2. Press firmly until each clip snaps into place
3. Run your hand along the edge to ensure it's fully seated

Step 8: Test the Door

1. Close the falcon wing door using the button
2. Listen for any unusual sounds
3. Check that the door seals properly (no gaps)
4. Test opening and closing several times
