Solution

1. Preparation

Gather necessary tools: OBD-II scanner, multimeter, socket set, and replacement fuses if needed.
Ensure the vehicle is parked on a flat surface and the ignition is off.

2. Inspect and Clean Window Switches

Sub-steps:
1. Remove the panel covering the window switches using a trim removal tool.
2. Disconnect the electrical connector from the switch.
3. Clean the switch terminals with electrical contact cleaner.
4. Reconnect the switch and reinstall the panel.

3. Check and Replace Fuses

Sub-steps:
1. Locate the fuse box (refer to the owner’s manual for exact location).
2. Identify the fuse for the power windows (typically labeled).
3. Remove the fuse using pliers and inspect it for continuity.
4. Replace the fuse with one of the same amperage if it is blown.
5. Reinstall the fuse cover and test the power windows.

4. Test Window Motor

Sub-steps:
1. Remove the door panel to access the window motor.
2. Disconnect the power connector from the window motor.
3. Use a multimeter to check for voltage when the switch is pressed.
4. If there is no voltage, trace the wiring back to the switch.
5. If voltage is present, replace the window motor.

5. Reassemble and Test

Sub-steps:
1. Reinstall the door panel and ensure all clips and screws are secure.
2. Reconnect the battery if it was disconnected.
