Solution

1. Preparation

Gather necessary tools and safety equipment.
Disconnect the vehicle battery to prevent electrical shock.
Ensure the vehicle is parked on a flat surface.

2. Check and Replace the Fuse

Locate the fuse box (usually under the dashboard or hood).
Identify the power window fuse using the diagram.
Remove the fuse using a fuse puller and inspect it for continuity.
- If blown: Replace with a new fuse of the same amperage.
- If intact: Proceed to the next step.

3. Inspect and Replace Window Switch

Remove the door panel using a socket set to access the window switch assembly.
Disconnect the window switch harness and inspect it for damage.
Test the switch with a multimeter for continuity.
- If faulty: Replace the window switch with a new one.
Reconnect the harness and reassemble the door panel.

4. Test Power Window Motor

Remove the door panel to access the window motor.
Disconnect the motor's electrical connector.
Use a multimeter to check for voltage at the motor connector while pressing the window switch.
- If no voltage: Check wiring to the switch.
- If voltage present: Replace the window motor.
To replace, remove the motor bolts and carefully pull the motor out, then install the new motor and secure it with bolts.

5. Reassemble and Test

Reattach the door panel, ensuring all clips and screws are secure.
Reconnect the vehicle battery.
Test all power windows to ensure they function properly.
