Solution

1. Preparation

Gather tools and parts: OBD-II scanner, multimeter, socket set, screwdriver set, replacement fuses, and window motor (if needed).
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuses

Sub-steps:
1. Locate the fuse box (typically under the dashboard or in the engine compartment).
2. Remove the cover and identify the fuse for the power windows (refer to the diagram on the fuse box cover).
3. Use a fuse puller or pliers to remove the fuse and check for continuity. Replace if blown.
4. Reinstall the fuse box cover and reconnect the battery.

3. Test Window Switches

Sub-steps:
1. Remove the door panel using a screwdriver and trim tools to access the switches.
2. Disconnect the switch connector and use a multimeter to check for continuity when pressing the switch.
3. If the switch is faulty, replace it with a new one.
4. Reassemble the door panel securely.

4. Check Window Motor

Sub-steps:
1. If the switches are functional, locate the window motor in the door.
2. Disconnect the motor connector.
3. Apply 12V directly to the motor terminals (ensure polarity is correct).
4. If the motor does not operate, replace it with a new window motor.
5. Reconnect the motor and reassemble the door panel.
