Solution

1. Preparation

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

2. Inspect and Replace the Fuse

Locate the fuse box (typically under the dashboard or in the engine compartment).
Identify the power window fuse using the diagram on the fuse box cover.
Remove the fuse and inspect it for a break or burn.
If blown, replace it with a fuse of the same amperage.

3. Test and Replace Window Switches

Remove the door panel to access the window switches.
Disconnect the electrical connector from the switch.
Use a multimeter to test for continuity. If there is no continuity, replace the switch.
Reconnect the new switch and reassemble the door panel.

4. Inspect and Replace Window Motors

If the switches are functional, check the window motors by removing the door panel.
Disconnect the motor's electrical connector and apply direct power from a 12V source to the motor.
If the motor does not operate, replace it with a new motor.
Reinstall the motor and ensure secure connections.

5. Check Wiring and Connections

Inspect the wiring harness running to the door for any damage or wear.
Repair or replace any damaged wires or connectors.
Ensure all connectors are clean and securely connected.
