Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the ignition is turned off.
Disconnect the vehicle battery to avoid any electrical shorts.

2. Inspect and Replace Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the cover of the fuse box and locate the power window fuse using the diagram on the cover.
Pull the fuse out using fuse pullers or pliers.
Inspect the fuse for continuity; if blown, replace it with a new fuse of the same amperage.

3. Check and Replace the Power Window Switch

Remove the door panel using a socket set to access the power window switch.
Disconnect the wiring harness from the switch.
Use a multimeter to check for continuity; if defective, replace the switch with a new one.
Reconnect the new switch to the wiring harness.

4. Inspect and Replace the Window Motor

If the switch is functional, remove the door panel to access the window motor.
Disconnect the motor's electrical connector.
Use a multimeter to check the motor for continuity; if faulty, replace it.
Remove the window motor from its mounting using a socket set and install the new motor.

5. Reassemble and Test

Reinstall the door panel and ensure all clips and screws are secured.
Reconnect the vehicle battery and test the window operation from the switch.
If the windows function correctly, ensure all components are properly secured.
