Solution

1. Preparation

Gather tools and materials: OBD-II scanner, multimeter, socket set, screwdrivers, replacement fuses, and window switches if necessary.
Disconnect the vehicle's battery to ensure safety during repairs.

2. Inspect and Replace Fuses

Locate the fuse box, typically found under the dashboard or near the driver's side.
Refer to the owner's manual to identify the specific fuse for the power windows.
Remove the fuse using a fuse puller or pliers and inspect it for continuity.
If blown, replace it with a fuse of the same amperage rating.

3. Check and Replace Window Switch

Remove the door panel using a screwdriver and trim removal tool to access the window switch.
Disconnect the wiring harness from the switch and inspect it for damage.
If the switch is faulty, replace it with a new one by reversing the removal process.

4. Test and Replace Window Motor (if necessary)

Reconnect the battery temporarily and test the window switch to see if the motor operates.
If still inoperative, disconnect the wiring harness from the window motor.
Use a multimeter to measure voltage at the motor connector while activating the switch.
If the motor does not receive power, check the wiring harness for issues. If voltage is present and the motor is still non-functional, replace the power window motor.

5. Reassemble Components

Once repairs are complete, reattach the door panel securely.
Ensure all clips and screws are fastened properly.
