1. Locate the fuse box (usually found under the dashboard or in the engine compartment).
2. Identify the power window fuse using the diagram on the fuse box cover.
3. Remove the fuse and check for continuity using a multimeter.
4. If blown, replace it with a fuse of the same amperage.

4. Test and Replace Window Motor (if necessary)

Sub-steps:
1. Gain access to the window motor by removing the door panel.
2. Disconnect the motor's electrical connector.
3. Apply direct power to the motor using jumper wires to see if it operates.
4. If the motor does not work, replace it with a new one, ensuring proper alignment when installing.
