Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect the Fuse

Tools Required: Fuse puller or needle-nose pliers
Locate the fuse box in the driver's side dashboard.
Remove the power window fuse and inspect it visually. If it is blown, replace it with a new fuse of the same amperage (usually 30A for power windows).

3. Test Power Window Switches

Tools Required: Multimeter
Reconnect the battery.
Remove the power window switch panel carefully.
Set the multimeter to continuity mode and check each switch for continuity when pressed. Replace the switches if they show no continuity.

4. Test the Window Motor

Tools Required: Jumper wires
Disconnect the window motor connector.
Using jumper wires, connect the motor directly to the vehicle’s battery (positive to one terminal, negative to the other). If the motor does not operate, it may need replacement.

5. Inspect Wiring Harness

Visually inspect the wiring harness leading to the door for any signs of fraying, cuts, or corrosion.
Repair any damaged wires by splicing or replacing as necessary. Ensure all connections are secure.

6. Reassemble Components

Reattach any panels or covers removed during the diagnostic process.
Ensure all screws and clips are secured.
