Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety while working on electrical components.
Tools Required:
- Socket set
- Multimeter
- Screwdriver set
- Trim removal tools

2. Check and Replace Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the power window fuse using the diagram on the fuse box cover.
Remove the fuse using pliers; check for continuity with a multimeter.
If blown, replace with a new fuse of the same amperage.

3. Inspect Window Switch

Remove the door panel using a trim removal tool.
Disconnect the power window switch connector.
Test the switch for continuity using a multimeter.
If defective, replace with a new switch.

4. Test Window Motor

With the door panel still removed, locate the window motor.
Disconnect the motor connector.
Using jumper wires, connect the motor directly to the vehicle battery to test its operation.
If the motor operates, check the wiring; if not, replace the window motor.

5. Inspect Window Regulator

If the motor is functioning, check the window regulator mechanism for damage or wear.
Remove the regulator from the door assembly if necessary, and inspect for any broken components.
Replace the regulator if it is found to be faulty.
