Solution

1. Preparation

Tools Required: Multimeter, OBD-II scanner, socket set, screwdrivers, wiring diagram.
Safety Warnings: Disconnect the vehicle battery before starting any electrical work.

2. Fuse Inspection

Locate the fuse box under the dashboard or hood.
Remove the power window fuse and inspect for continuity using a multimeter.
If the fuse is blown, replace it with one of the same amperage.

3. Switch Inspection

Remove the door panel using a screwdriver and trim removal tool.
Disconnect the power window switch connector.
Inspect the switch for damage; if necessary, replace the switch.

4. Wiring Inspection

Using the wiring diagram, trace the wiring from the switch to the window motor.
Check for any breaks or frays in the wiring.
Test for voltage at the connector of the window motor while operating the switch.

5. Motor Test

If the wiring is intact, remove the window motor from the door.
Connect the motor directly to a power source (e.g., a car battery) to check if it operates.
If the motor does not operate, it may need replacement.

6. Reassembly

Once repairs are completed, reassemble the door panel carefully.
Reconnect the battery and test the power windows to ensure they operate correctly.
