Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to prevent any electrical shock or short circuits.
Ensure the work area is clear and safe.

2. Inspect and Test the Window Lock Switch

Locate the window lock switch on the driver’s door panel.
Ensure the switch is in the "unlocked" position.
If necessary, clean the switch with electrical contact cleaner to remove any debris.

3. Check and Replace Fuses

Open the fuse box located under the dashboard or in the engine compartment.
Locate the fuse for the power windows using the diagram on the fuse box cover.
Use a fuse puller to remove the fuse and inspect it for continuity.
Replace with a fuse of the same amperage if blown.

4. Test the Window Switch

Remove the door panel to access the window switch.
Disconnect the switch connector.
Use a multimeter to measure continuity across the switch terminals while pressing the switch.
Replace the switch if continuity is not present.

5. Inspect the Wiring and Window Motor

Check the wiring harness for any signs of damage, corrosion, or loose connections.
If the wiring appears intact, apply direct battery power to the window motor terminals.
If the motor operates, it may indicate a faulty switch or wiring issue. If it does not operate, replace the window motor.
