Solution

1. Preparation

Tools Required:
- Multimeter
- Screwdriver set
- Wiring diagram (from manual)
Disconnect the battery to ensure safety while working with electrical components.

2. Check and Replace the Fuse

Locate the fuse box and identify the power window fuse using the diagram.
Remove the fuse and inspect it for continuity.
If blown, replace it with a new fuse of the same amperage.

3. Inspect and Replace the Window Switch

Remove the door panel using a screwdriver to access the window switch.
Disconnect the wiring harness from the switch.
Test the switch with a multimeter for continuity.
If faulty, replace with a new switch and reconnect wiring.

4. Test and Replace the Window Motor

Access the window motor by removing the door panel.
Disconnect the harness from the motor.
Use a multimeter to check for power at the motor terminals while activating the switch.
If no power is present, the wiring may need repair. If power exists but the motor does not operate, replace the motor.

5. Inspect the Wiring Harness

Visually inspect the wiring harness for any signs of wear, fraying, or corrosion.
Repair or replace damaged wiring sections as needed to ensure proper electrical continuity.

6. Reassemble and Test

Reinstall the door panel and any components removed during the repair.
Reconnect the battery and test the window operation from the master switch and individual switches.
