Solution

1. Preparation

Gather all required tools and parts.
Disconnect the negative battery terminal to prevent electrical shock.
Ensure the vehicle is parked securely.

2. Inspect and Replace Fuse

Tools Required: Fuse puller or needle-nose pliers
Locate the power window fuse in the fuse box (refer to the owner's manual for the exact location).
Remove the fuse and check for continuity using a multimeter.
- If blown, replace it with a fuse of the same amperage (typically 30A).

3. Test and Replace Power Window Switch

Tools Required: Multimeter, small flathead screwdriver
Remove the power window switch panel using the flathead screwdriver.
Disconnect the switch connector and use a multimeter to test for continuity.
- If the switch is faulty, replace it with a new switch.

4. Check Window Motor

Tools Required: Multimeter, jumper wires
Disconnect the window motor connector.
Use jumper wires to apply direct battery voltage to the motor terminals.
- If the motor operates, it may be the switch or wiring; if not, replace the motor.

5. Inspect Window Regulator

Tools Required: Torx or socket set
Remove the door panel to access the window regulator.
Inspect for any broken or jammed components.
Replace the window regulator if damaged.

6. Reassemble and Test

Reconnect any components removed during the process.
Reattach the door panel securely.
Reconnect the negative battery terminal and test all power windows for functionality.
