Solution

1. Preparation

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

2. Check Fuses

Locate the fuse box, typically under the dashboard or in the engine compartment.
Identify the fuse related to power windows using the diagram on the fuse box cover.
Remove the fuse with a fuse puller and inspect it. Replace if blown.
Reconnect the battery and test the windows.

3. Inspect Switches

Remove the door panel using a screwdriver and trim removal tools.
Disconnect the window switch harness.
Use a multimeter to test the switch for continuity when pressed.
Replace the switch if it fails the continuity test.

4. Check Wiring and Connections

Visually inspect the wiring harness connected to the window motor for any wear or damage.
Look for loose connections or corrosion at the connectors.
Repair or replace damaged wiring as necessary.

5. Test Window Motor

Disconnect the window motor from the wiring harness.
Using jumper wires, connect the motor directly to the vehicle battery.
If the motor operates, it may need replacement; if it does not, further electrical issues may exist.

6. Reassemble Components

Reattach any removed connectors and ensure all wiring is secure.
Reinstall the door panel by aligning it and securing it with screws.
Reconnect the battery.
