Solution

1. Preparation

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

2. Inspect and Replace the Fuse

Locate the fuse box (usually under the dashboard or in the engine bay).
Identify the power window fuse, usually labeled in the cover diagram.
Remove the fuse using a fuse puller or needle-nose pliers.
Inspect the fuse; if it’s blown, replace it with a new fuse of the same amperage.

3. Test the Power Window Switch

Reconnect the battery.
Using a multimeter, set to DC voltage, press the power window switch while testing the voltage at the switch terminals.
If there is no voltage, the switch may need replacement.

4. Check Wiring and Connectors

Inspect the wiring harness for any visible damage or fraying.
Ensure all connectors are securely attached and free of corrosion.
Repair or replace any damaged wiring or connectors as necessary.

5. Test and Replace the Power Window Motor

Disconnect the motor's electrical connector.
Use jumper wires to connect the motor directly to the battery (positive to positive and negative to negative).
If the motor does not operate, replace it.

6. Inspect and Replace the Window Regulator (if necessary)

Remove the door panel to access the window regulator.
Check for mechanical obstructions or damage to the regulator.
If damaged, unbolt the regulator and replace with a new unit, ensuring all connections are secure.
