Solution

1. Preparation

Gather necessary tools: OBD-II scanner, multimeter, basic socket set, wire stripper, and electrical tape.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect and Replace Window Switches

Remove the door panel:
- Use a socket set to remove screws holding the door panel.
- Carefully pry off the panel using a trim tool to avoid damage to clips.
Access the window switch:
- Disconnect the switch harness from the back of the window switch.
Test or replace the switch:
- Use a multimeter to check continuity across switch terminals.
- If defective, replace with a new switch and reconnect the harness.

3. Check and Replace Fuses

Locate the fuse box:
- Refer to the owner's manual to find the precise location of the fuse box.
Inspect the fuse for power windows:
- Identify the fuse related to the power windows and remove it using a fuse puller.
- Check for continuity using a multimeter; replace if blown.

4. Test and Replace Window Motor

Access the window motor:
- If the switches and fuses are functional, remove the door panel again.
- Disconnect the motor harness.
Directly test the window motor:
- Connect the motor to a 12V power source to check operation.
- If the motor does not operate, replace it with a new window motor.

5. Inspect Wiring Harness

Check for damage:
- Visually inspect the wiring harness for frays, cuts, or corrosion.
Repair any damage:
- Use wire strippers to clean up any damaged sections and splice with new wire as needed.
- Secure with electrical tape to prevent shorts.
