2. Check and Replace the Fuse

Locate the fuse box, typically 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 a fuse puller or pliers.
Inspect the fuse; if blown, replace it with a fuse of the same amperage.

3. Inspect and Replace the Window Switch

Remove the door panel using a trim removal tool to access the window switch.
Disconnect the wiring harness from the switch.
Test the switch with a multimeter for continuity; if faulty, replace it with a new switch.
Reconnect the wiring harness and reassemble the door panel.

4. Inspect and Replace the Window Regulator

If the switch is functional, check the window regulator and motor.
Disconnect the window motor wiring harness.
Use a socket set to remove the bolts securing the window regulator to the door.
Carefully remove the window regulator; if it is damaged or the motor is faulty, replace it with a new unit.
Reinstall the new regulator and motor, ensuring all bolts are torqued to manufacturer specifications.
