Solution

1. Preparation

Gather tools: socket set, multimeter, screwdrivers, and replacement fuses if necessary.
Disconnect the vehicle's battery to ensure safety while working on electrical components.

2. Check and Replace Fuse

Locate the fuse box (usually found under the dashboard or in the engine compartment).
Remove the cover and locate the power window fuse.
Visually inspect the fuse for damage; if it's blown, replace it with a fuse of the same amperage rating.

3. Inspect and Repair Wiring

Remove the door panel using a screwdriver and trim tool.
Inspect the wiring harness for any damaged or frayed wires.
Repair or replace any damaged wiring using electrical tape or soldering as necessary.
Ensure all connections are secure and free from corrosion.

4. Test Switch and Motor

Remove the window switch from the door panel.
Use a multimeter to check for continuity in the switch.
If the switch is faulty, replace it with a new one.
For window motor testing, connect the motor directly to a 12V power source to determine if it functions.

5. Reassemble and Final Checks

Reattach the door panel, ensuring all clips and screws are secured.
Reconnect the vehicle's battery.
Test each power window to verify that they are functioning correctly.
