Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is in the off position.
Disconnect the negative battery terminal to avoid electrical shock.

2. Inspect and Replace the Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the cover and identify the power window fuse using the diagram.
Pull the fuse using a fuse puller. Inspect it for continuity; replace if blown with the same amperage rating.

3. Test the Window Switch

Remove the switch panel by gently prying it up with a trim removal tool.
Disconnect the switch connector and set your multimeter to continuity mode.
Test the terminals; if there is no continuity, replace the switch.

4. Check Window Motor Operation

Remove the door panel using a socket set to access the motor.
Locate the window motor connector and check for voltage when the switch is pressed.
If voltage is present and the motor does not work, replace the window motor.

5. Inspect Wiring and Connectors

Examine the wiring harness for frays, breaks, or corrosion.
Repair any damaged wires using solder and heat-shrink tubing or replace the entire harness if necessary.

6. Reassemble and Test

Reattach the door panel and ensure all clips and screws are secured.
Reconnect the negative battery terminal.
Test the power windows by operating each switch.
