Solution

1. Preparation

Gather tools: multimeter, socket set, flathead screwdriver, and Tesla diagnostics tool.
Park the vehicle in a safe area and ensure it is powered off.

2. Inspect and Replace Fuse

Locate the power window fuse in the fuse box (refer to the owner's manual for exact location).
Using a socket set, remove the fuse.
Inspect the fuse visually; if blown, replace it with a new fuse of the same amperage.

3. Test and Replace Window Switch

Remove the door trim panel using a flathead screwdriver to access the window switch assembly.
Disconnect the window switch connector and test for continuity across the terminals with a multimeter.
If continuity is absent, replace the window switch with a new one.

4. Inspect Wiring and Connectors

Inspect the wiring harness leading to the window motor for any signs of wear, fraying, or breaks.
Check connectors for corrosion or poor connections; clean or replace as necessary.

5. Test Window Motor

Remove the window motor from the door panel.
Connect the motor directly to a 12V power source to verify operation.
If the motor does not function, replace it with a new window motor.

6. Reassemble and Test

Reassemble the door trim panel and ensure all clips and screws are secured.
Restore power and test all power windows to verify proper operation.
