Solution

1. Preparation

Gather necessary tools: multimeter, flathead screwdriver, Phillips screwdriver, socket set, and a trim removal tool.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Check and Replace Fuses

Locate the fuse box under the dashboard or in the engine compartment.
Identify the fuse related to the power windows using the diagram on the fuse box cover.
Remove the fuse using a fuse puller or pliers. Inspect it for continuity; replace it if blown with a fuse of the same amperage.

3. Inspect and Replace Power Window Switch

Remove the door panel using a trim removal tool to access the power window switch.
Disconnect the electrical connector from the switch.
Test the switch with a multimeter to check for continuity; replace if faulty.
Reinstall the new switch by reversing the removal steps.

4. Test and Replace Window Motor

Remove the door panel to access the window motor and regulator.
Disconnect the wiring harness from the window motor.
Use a multimeter to test for voltage at the motor connector while activating the switch.
If voltage is present but the motor does not operate, replace the motor.
If voltage is absent, trace back to the switch or wiring for further issues.

5. Reassemble and Test

Reinstall the door panel and ensure all clips are secured.
Reconnect the battery and test the power windows to confirm functionality.
