Tools Required: Socket set, Torque wrench, Multimeter, Screwdriver set, Wire stripper/crimper

2. Inspect and Replace the Fuse

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

3. Test and Replace the Power Window Switch

Remove the switch panel using a screwdriver; gently pry it out to avoid breaking clips.
Disconnect the electrical connector from the switch.
Use a multimeter to test the switch for continuity when pressed; replace if defective.
Reconnect the new switch and ensure it fits securely.

If the switch is functioning, the next step is to inspect the window motor.
Remove the door panel to access the power window motor; use a socket set to remove screws and clips.
Disconnect the motor’s electrical connector.
Test the motor with a multimeter by applying direct power; if it does not operate, replace the motor.
Install the new motor and reconnect the electrical connector.

5. Reassemble and Test
