Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to ensure safety during the repair.
Tools Required:
- Socket set
- Screwdrivers (flathead and Phillips)
- Multimeter
- Wire strippers and connectors (if needed)

2. Check and Replace the Fuse

Locate the fuse box under the dashboard or in the engine compartment.
Identify the power window fuse using the diagram on the fuse box cover.
Remove the fuse and inspect it; replace it if it is blown.
Reconnect the battery and test the windows.

3. Inspect and Test the Power Window Switch

Remove the door panel using a screwdriver and trim tool to access the window switch.
Disconnect the switch connector and use a multimeter to test for continuity.
If the switch is faulty, replace it with a new one.
Reconnect the switch and reassemble the door panel.

4. Test the Window Motor

If the switch is functioning, disconnect the window motor from its wiring harness.
Using a multimeter, test for voltage at the motor connector when the switch is pressed.
If there is voltage but the motor does not work, replace the window motor.
If there is no voltage, trace back to the switch or wiring for faults.

5. Inspect and Replace the Window Regulator

If the motor is operational but the window does not move, the window regulator may be faulty.
Remove the door panel again, and disconnect the motor.
Remove the window regulator from the door, being careful with any clips or screws.
Install the new regulator and reattach the window motor.
Reassemble the door panel and test the windows.
