Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.

2. Check and Replace Fuses

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the cover and identify the power window fuse using the diagram on the fuse box cover.
Inspect the fuse visually; if it is blown, remove it and replace it with a new fuse of the same amperage (typically 30A).

3. Test and Replace Window Switch

Remove the door panel to access the window switch.
Disconnect the wiring harness from the switch.
Use a multimeter to test the switch for continuity; if it is faulty, replace it with a new switch.

4. Inspect and Replace Power Window Motor

If the switch is functional, locate the power window motor inside the door.
Disconnect the wiring harness from the motor.
Test for voltage at the motor terminals when the switch is activated. If there is power but the motor doesn't work, remove the motor:
- Unscrew the mounting bolts securing the motor.
- Carefully pull the motor out of the assembly.
- Install the new motor by reversing these steps and secure it properly.
