Solution

1. Preparation

Tools Required: Basic hand tools, multimeter, OBD-II scanner
Safety Warnings: Disconnect the vehicle battery before working on electrical systems.

2. Inspect and Replace Fuse

Locate the fuse box (typically under the dashboard or in the engine compartment).
Remove the power window fuse using a fuse puller.
Inspect the fuse visually and test with a multimeter for continuity.
If blown, replace the fuse with one of the same amperage.

3. Test and Replace Power Window Switch

Remove the door panel to access the power window switch.
Disconnect the wiring harness from the switch.
Use a multimeter to test the switch for continuity.
If there is no continuity, replace the switch with a new one.
Reconnect the switch and reassemble the door panel.

4. Inspect and Replace Power Window Motor

If the switch is functioning, access the window motor by removing the door panel.
Disconnect the motor's wiring harness.
Apply direct battery voltage to the motor's terminals to test its operation.
If the motor does not operate, remove it and replace it with a new unit.
Reinstall the motor and reconnect the wiring harness.

5. Reconnect and Test

Reconnect the vehicle battery.
Test the operation of the power windows using the switch.
Ensure that all components are functioning correctly before final assembly.
