Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface with the ignition off.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Remove the cover and consult the fuse diagram to find the power window fuse.
Inspect the fuse for continuity using a multimeter; if blown, replace it with a new fuse of the same amperage.

3. Test and Replace Power Window Switch

Remove the power window switch panel from the door.
Using a multimeter, check for continuity on the switch terminals when pressed.
If the switch fails the test, replace it with a new one by disconnecting the wiring harness and reinstalling the new switch.

4. Inspect Wiring and Connectors

Visually inspect the wiring harness leading to the power window motor for any signs of wear, fraying, or disconnection.
If damaged, repair the wiring using solder and heat shrink tubing or replace the entire harness if necessary.

5. Test and Replace Window Motor

Remove the door panel to access the power window motor.
Disconnect the motor harness and test the motor by applying direct battery voltage to see if it operates.
If the motor does not work, replace it by unscrewing it from the door frame and installing a new motor.
