Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, flathead screwdriver, and safety glasses.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Fuse Inspection

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the cover and locate the power window fuse.
Inspect the fuse for continuity using a multimeter; replace if blown.

3. Switch Testing

Remove the door panel using a flathead screwdriver to access the switches.
Disconnect the switch connector and test each terminal with a multimeter for proper voltage.
Replace the switch if it fails the test.

4. Window Motor and Regulator Inspection

Remove the door panel completely to access the window motor and regulator assembly.
Disconnect the motor from the wiring harness.
Use jumper wires to connect the motor directly to the battery. If the motor does not operate, replace it.
Inspect the window regulator for any signs of wear or obstruction and replace if necessary.

5. Reassembly

Reconnect all electrical connectors and ensure all bolts and screws are tightened to their original positions.
Reinstall the door panel, ensuring clips are secured.
Reconnect the negative battery terminal.
