Solution

1. Preparation

Gather tools: socket set, multimeter, OBD-II scanner, screwdrivers, and a replacement fuse if necessary.
Disconnect the negative battery terminal to prevent any electrical shorts.

2. Replace Fuse (if blown)

Locate the fuse panel according to the owner’s manual.
Remove the blown fuse using a fuse puller or pliers.
Insert a new fuse of the same amperage rating.
Reconnect the negative battery terminal.

3. Repair or Replace Window Switch

Remove the door panel to access the window switch assembly; typically requires a screwdriver and trim removal tools.
Disconnect the wiring harness from the window switch.
Test the switch with a multimeter; if faulty, replace it with a new switch.
Reconnect the wiring harness and reattach the door panel.

4. Repair or Replace Window Motor/Regulator

If the motor is faulty, remove the door panel and disconnect the motor's wiring harness.
Remove the screws or bolts securing the window motor and regulator assembly.
Carefully detach the window from the regulator (may require raising the window).
Install the new motor or regulator by reversing the removal steps, ensuring all fasteners are torqued to manufacturer's specifications.
