Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Identify the power window fuse in the owner’s manual.
Remove the fuse using a fuse puller and inspect for a blown element.
Replace with a new fuse of the same amperage if necessary.

3. Test and Replace Switch

Remove the door panel using a trim tool to access the power window switch.
Disconnect the switch connector.
Use a multimeter to check for continuity across switch terminals when pressed.
Replace the switch if it does not show continuity.

4. Inspect Wiring and Connectors

Visually check the wiring harness for any signs of wear, fraying, or corrosion.
Clean any corroded connectors with electrical contact cleaner.
Repair or replace damaged wiring as necessary.

5. Test Window Motor

Disconnect the window motor from the regulator.
Use jumper wires to connect the motor directly to the battery (positive to positive and negative to negative).
If the motor operates normally, the issue may lie with the switch or wiring; if it does not, replace the motor.

6. Check and Replace Window Regulator

If the motor works but the window does not move, inspect the window regulator.
Remove the regulator from the door panel by unscrewing it and disconnecting any clips.
Replace the regulator if it is damaged or not functioning properly.
