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.
Use a fuse puller or pliers to remove the fuse.
Inspect the fuse for continuity; replace it with a new fuse of the same amperage if blown.

3. Inspect and Replace the Window Switch

Remove the door panel using a trim removal tool and screws (if applicable).
Disconnect the window switch harness from the door panel.
Test the switch with a multimeter; replace it if it shows no continuity when pressed.
Install the new switch by reconnecting the harness and securing it in place.

4. Test the Window Motor

With the door panel removed, locate the window motor.
Reconnect the battery and use a multimeter to check for voltage at the motor terminals when the switch is activated.
If power is present but the motor does not operate, replace the window motor by:
- Removing the motor mounting screws.
