Solution

1. Preparation

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

2. Check and Replace Fuses

Tools Required: Fuse puller or needle-nose pliers.
Locate the fuse box (usually under the dashboard or in the engine compartment) and identify the fuse for the power windows.
Remove the fuse and visually inspect it. If the wire is broken, replace it with a new fuse of the same amperage.
Reconnect the battery and test the power windows to see if the issue is resolved.

3. Inspect and Replace the Switch

Tools Required: Screwdriver set, multimeter.
Remove the door panel using a screwdriver to access the power window switch.
Disconnect the wiring harness from the switch and test for continuity using a multimeter.
If the switch shows no continuity, replace it with a new switch.
Reinstall the door panel and reconnect the battery to test functionality.

4. Test and Replace the Window Motor

Tools Required: Screwdriver set, multimeter, power supply (12V battery).
Remove the door panel to access the window motor.
Disconnect the motor's wiring harness and use a multimeter to check for voltage at the motor when the switch is pressed.
If there’s voltage, the motor may be faulty. Apply 12V directly to the motor terminals to test if it operates.
If the motor does not work, replace it with a new motor and reassemble the door panel.

5. Inspect Wiring and Connectors

Inspect the wiring harness for any frays, breaks, or corrosion.
If any damage is found, repair or replace the affected wires and connectors.
Ensure all connections are secure and properly insulated.
