Solution

1. Preparation

Gather tools: socket set, multimeter, flathead screwdriver, Torx screwdriver, and replacement parts as needed.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect and Replace the Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Use the fuse puller or pliers to remove the power window fuse.
Inspect the fuse for continuity; replace with the same amperage if blown.

3. Replace the Power Window Switch (if needed)

Remove the door panel using a flathead screwdriver to pry off clips.
Unscrew and disconnect the power window switch from the panel.
Install the new switch by reversing the removal steps.

4. Test and Replace the Window Motor (if needed)

Remove the door panel to access the window motor.
Disconnect the wiring harness from the motor.
Use a multimeter to test the motor for voltage while activating the switch; if no voltage, further wiring inspection is needed.
If the motor is faulty, unbolt and remove it from the regulator assembly.
Install the new motor by securing it in place and reconnecting the wiring harness.

5. Check and Replace the Window Regulator (if needed)

If the motor is functional but the window does not move, inspect the regulator.
Remove the window from the regulator by carefully detaching it.
Unbolt and remove the faulty window regulator.
Install the new regulator, ensuring it is aligned correctly, and reattach the window.

6. Reassemble the Door Panel

Carefully reposition the door panel and press it back into place, ensuring all clips are secured.
Reinstall screws for the door handle and power window switch.
Reconnect the vehicle battery.
