Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, screwdrivers, and a socket set.
Ensure the vehicle is in 'Park' and the ignition is off.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Test the Window Switch

Remove the door panel to access the window switch.
- Use a screwdriver to remove screws securing the door panel.
- Carefully pry off the panel using a trim removal tool.
Disconnect the window switch connector.
Use a multimeter to test for continuity across the switch terminals.
- If there is no continuity, replace the window switch.

3. Check and Replace the 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 using a fuse puller and inspect it.
- If the fuse is blown, replace it with one of the same amperage rating.

4. Inspect Wiring and Connections

While the door panel is removed, visually inspect the wiring harness for any frayed or damaged wires.
Check for loose connections at the window motor and switch.
If any issues are found, repair or replace the damaged wiring.

5. Test the Window Motor

If the switch and wiring are functional, test the window motor by applying power directly to it.
If the motor does not operate, it may need to be replaced.
To replace the motor:
- Remove the window regulator assembly from the door.
- Disconnect the motor from the regulator and replace it with a new unit.
