Solution

1. Preparation

Gather necessary tools and safety equipment.
Ensure the vehicle is in park and the ignition is off.
Disconnect the negative terminal of the battery for safety.

2. Inspect and Replace Fuses

Locate the fuse box; refer to the owner's manual for the exact location.
Identify the fuse associated with the power windows (usually labeled).
Use a fuse puller or pliers to remove the fuse and visually inspect it for damage.
If the fuse is blown, replace it with one of the same amperage (check the owner's manual for specifications).
Reconnect the battery and test the windows.

3. Check and Replace Window Switches

If fuses are intact, proceed to remove the door panel to access the window switches.
Use a trim removal tool to carefully detach the door panel without causing damage.
Disconnect the wiring harness for the window switch and test with a multimeter for continuity.
If the switch is faulty, replace it with a new switch compatible with the Tesla Model S.
Reassemble the door panel and test the window functionality.

4. Inspect Window Motor and Wiring

If the switches are functional, check the window motor by removing it from the door assembly.
Test the motor by applying direct power from the battery to see if it operates.
Inspect the wiring harness for any signs of damage or corrosion.
Replace the window motor if it fails to operate with direct power.
