Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to avoid any electrical shorts.

2. Inspect the Window Switch

Remove the switch panel using a trim removal tool.
Disconnect the electrical connector from the switch.
Use a multimeter to test for continuity across the switch terminals when pressed.
If the switch is faulty, replace it with a new one.

3. Check the Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the fuse for the power windows using the owner's manual or fuse diagram.
Remove the fuse and inspect it for continuity. Replace if blown.

4. Inspect Wiring and Connectors

Visually inspect the wiring harness connected to the window switch and motor for any frayed wires or corrosion.
Clean any corroded connectors with electrical contact cleaner.
Ensure all connections are secure and reassemble.

5. Test the Window Motor

Disconnect the window motor from the regulator.
Using jumper wires, apply 12V directly to the motor terminals (be cautious of polarity).
If the motor operates, the issue may be with the regulator or wiring. If it does not run, replace the window motor.

6. Examine the Window Regulator

If the motor is functional, check the window regulator for any binding or mechanical failure.
Remove the door panel to access the regulator.
Inspect for broken cables or damaged gears, and replace the regulator if necessary.
