Solution

1. Preparation

Gather tools: Multimeter, socket set, wire stripper/crimper, screwdriver set, and replacement parts if needed.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuses

Locate the fuse box (usually found under the driver's side dashboard or under the hood).
Remove the power window fuse using a fuse puller or needle-nose pliers.
Inspect the fuse for continuity. If blown, replace it with a new fuse of the same amperage.

3. Replace the Window Switch or Motor if Necessary

A. Window Switch

Remove the door panel using a screwdriver and trim tool to access the window switch.
Disconnect the electrical connector from the switch.
Test the switch for continuity with a multimeter. If defective, replace it with a new switch.
Reconnect the new switch and reassemble the door panel.

B. Window Motor

If the switch is functional, check the window motor. Remove the door panel as described above.
Disconnect the motor's electrical connector.
Using a multimeter, check for power at the motor connector when the switch is pressed.
If no power is present, trace back to the switch or fuse. If power is present but the motor does not operate, replace the motor.
Install the new motor by securing it to the window regulator and reconnecting the electrical connector.

4. Reassemble and Test

Reattach the door panel securely, ensuring all clips and screws are in place.
Reconnect the battery and test the window operation using the switch.
