Solution

1. Preparation

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

2. Inspect and Replace the Fuse

Locate the fuse box (typically under the dashboard or in the engine compartment).
Remove the power window fuse using a fuse puller or pliers.
Check the fuse for continuity with a multimeter. Replace it if it is blown with a fuse of the same amperage.

3. Test and Replace Window Switches

Remove the door panel to access the power window switch assembly.
Disconnect the wiring harness from the switch.
Use a multimeter to test for continuity in the switch. Replace the switch if it fails.

4. Check Wiring and Connectors

Inspect the wiring harness for any frayed wires or loose connections.
Repair any damaged wires or connectors as necessary using solder or crimp connectors.
Ensure all connections are securely reattached.

5. Test and Replace Window Motors

If the switches and wiring are intact, access the window motor by removing the door panel.
Disconnect the motor's wiring harness.
Use jumper wires to connect the motor directly to the battery to test for functionality. Replace the motor if it does not operate.

6. Reassemble and Test

Reattach the door panel, ensuring all clips and screws are secured.
Reconnect the vehicle battery.
Test the power windows to ensure they are functioning correctly.
