Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, safety gloves.
Disconnect the high-voltage battery pack for safety.

2. Inspect and Replace Fuses

Locate the fuse box, usually found in the front trunk (frunk).
Identify the fuse for the power windows (refer to the owner's manual for the specific fuse location).
Use a fuse puller to remove the fuse and inspect for continuity. Replace with a fuse of the same amperage if blown.

3. Testing and Replacing Window Switches

Remove the door panel using a socket set to access the window switch assembly.
Disconnect the wiring harness from the switch.
Test the switch with a multimeter for continuity; replace if faulty.
Reconnect the new switch and reassemble the door panel.

4. Inspecting and Replacing Window Motors

If the switches are functional, remove the door panel to access the window motor.
Disconnect the motor's wiring harness.
Test the motor with a multimeter for functionality; replace if defective.
Install the new motor and reassemble the door panel.
