Solution

1. Preparation

Tools Required:
- Screwdriver set
- Multimeter
- Torque wrench
- Wire strippers
Disconnect the negative battery terminal to ensure safety while working on the electrical components.

2. Check and Replace Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the power window fuse using the diagram on the fuse box cover.
Remove the fuse and inspect it for continuity.
- If blown, replace it with a fuse of the same amperage.

3. Inspect and Test Relay

Locate the power window relay, usually found in the relay box.
Remove the relay and test it for continuity using a multimeter.
- If defective, replace with a new relay of the same specifications.

4. Test Window Switch

Remove the door panel using a screwdriver to access the window switch.
Disconnect the switch connector and use a multimeter to check for voltage when the switch is pressed.
- If no voltage is present, the switch may need to be replaced.

5. Examine the Window Motor

With the door panel removed, locate the window motor.
Disconnect the motor's electrical connector and apply direct battery power to the motor.
- If the motor operates, it may require replacement or further inspection of the wiring.

6. Reassemble Components

Reinstall the door panel and ensure all clips and screws are securely fastened.
Reconnect the negative battery terminal.
