Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the vehicle battery to avoid electrical shock.
Remove the door panel to access the window components.

2. Inspect and Replace the Fuse

Locate the fuse box (often under the dashboard or in the engine compartment).
Identify the power window fuse (refer to the diagram in the fuse box cover).
Remove the fuse using a fuse puller and inspect it for continuity.
Replace with a new fuse of the same amperage if blown.

3. Test and Replace the Window Switch

Locate the window switch (usually on the driver's door).
Remove the switch panel carefully using a flathead screwdriver.
Disconnect the switch wiring harness and test for continuity using a multimeter.
If faulty, replace the switch with a new one.

4. Check and Replace the Window Motor

With the door panel removed, locate the window motor attached to the window regulator.
Disconnect the motor wiring harness.
Apply direct voltage to the motor terminals to check if it operates.
If it does not work, remove the motor using the appropriate socket wrench and replace it with a new one.

5. Inspect and Repair the Window Regulator

Check the window regulator for any mechanical issues such as bending or binding.
If damaged, remove the regulator from the door assembly (usually secured with bolts).
Install a new window regulator by reversing the removal process.
