Solution

1. Preparation

Gather tools and materials: OBD-II scanner, multimeter, socket set, and a screwdriver.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Check and Replace Fuse

Locate the fuse box: Refer to the owner's manual for the exact location of the power window fuse.
Inspect the fuse: Remove the fuse and visually inspect for a break. Use a multimeter to check for continuity.
Replace if necessary: If the fuse is blown, replace it with a fuse of the same amperage.

3. Test Window Switch

Remove the switch panel: Use a screwdriver to carefully pry off the switch panel from the door.
Check connections: Inspect the wiring harness for any loose connections or damage.
Test the switch: Use a multimeter to measure the resistance across the switch terminals when pressed. Replace the switch if it is faulty.

4. Test Window Motor

Access the window motor: Remove the door panel using a socket set and screwdriver.
Disconnect the motor: Unplug the motor connector.
Direct power test: Apply direct battery voltage to the motor terminals to check for operation. If the motor does not operate, it may need replacement.

5. Examine Wiring and Connectors

Inspect wiring: Look for frayed wires or signs of wear along the door harness.
Check connectors: Ensure all connectors are secure and free of corrosion. Clean any corroded connections with electronic contact cleaner.
