Repair Instructions

Step 1: Address Obstructions

1. Clear Debris:
   • Open the door and inspect the window tracks for any debris or ice.
   • Clean the tracks using a soft brush and a cloth.

Step 2: Check and Replace Window Switch

1. Remove Door Panel:

   • Use a trim removal tool to carefully pry off the door panel clips.
   • Remove screws securing the panel (if applicable).
   • Disconnect the electrical connectors for the window switches.

2. Test the Switch:

   • Use a multimeter to test for continuity when pressing the switch.
   • If defective, replace the switch with a new part.

3. Reassemble:

   • Reconnect the electrical connectors and carefully reattach the door panel.

Step 3: Reset the Window Function

1. Window Calibration:
   • Fully open the window using the switch.
   • Hold the switch at the open position for 5 seconds.
   • Close the window and hold the switch at the closed position for another 5 seconds.
   • This recalibrates the window position sensor.

Step 4: Check Window Motor and Mechanism

1. Inspect Motor Function:

   • If the window does not operate, remove the door panel again.
   • Disconnect the window motor connector and test it with a multimeter for power when the switch is activated.

2. Replace Motor if Necessary:

   • If no power is detected, trace wiring back to the switch and check for continuity.
   • If the motor is defective, remove it by unscrewing the mounting bolts and replacing it with a new motor.

3. Check the Regulator:

   • Inspect the window regulator for any signs of wear or damage. If it is damaged, replace it as well.

Step 5: Final Checks

1. Reassemble the Door Panel:

   • Replace the door panel by reversing the disassembly steps.
   • Make sure all clips and screws are properly secured.

2. Test Windows:

   • Test all window functions to ensure that they operate smoothly and seal correctly.
   • Listen for any unusual noises during operation.

Conclusion

If the automatic window function still does not operate correctly after following these steps, consider consulting a Tesla certified technician for further diagnosis. Additionally, ensure that your vehicle is running the latest software version, as updates may rectify some issues related to electric windows.
