Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to avoid electrical shock.

2. Check and Replace Fuses

Tools Required: Fuse puller or needle-nose pliers
Locate the fuse box; consult the owner's manual for the specific fuse related to power windows.
Remove the fuse and inspect it for continuity; replace if blown.

3. Inspect and Replace Window Switch

Tools Required: Flathead screwdriver, Torx screwdriver
Remove the door panel using the screwdriver to access the window switch.
Disconnect the wiring harness from the switch and check for damage.
If damaged, replace with a new switch; ensure it is securely connected.

4. Test and Replace Window Motor

Tools Required: Multimeter, 12V power supply, socket set
Disconnect the wiring harness from the window motor.
Use the multimeter to check for voltage when the switch is pressed.
If no voltage is present, the issue might be upstream. If voltage is present, connect the motor to a 12V power supply directly to test.
Replace the motor if it does not operate when powered directly.

5. Reassemble and Test

Reinstall the door panel and reconnect the battery.
Test the power windows to ensure they operate correctly.
