Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and a trim removal tool.
Ensure the vehicle is parked on a level surface and turned off.
Disconnect the vehicle's 12V battery to prevent any electrical shorts.

2. Inspect and Replace Window Switches

Remove the door panel using a trim removal tool.
Disconnect the window switch connector.
Test the switch with a multimeter, checking for continuity when pressed.
If faulty, replace the switch with a new one and reconnect.

3. Reset the Windows

Reconnect the 12V battery.
Access the Tesla service menu via the touchscreen.
Navigate to the "Controls" > "Windows" section.
Select the option to reset the windows. Follow the prompts to calibrate.

4. Check Window Motors

Remove the door panel again to access the window motor.
Disconnect the motor connector and test voltage with a multimeter while activating the window switch.
If no voltage is present, trace wiring for issues; if voltage is present but the motor does not operate, replace the window motor.

5. Clean and Lubricate Window Tracks

Remove any debris from the window tracks.
Apply a silicone-based lubricant to the tracks to ensure smooth operation.
Reinstall the door panel securely.
