Solution

1. Preparation

Gather tools: socket set, multimeter, flathead screwdriver, and a replacement fuse (if necessary).
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Fuse

Locate the fuse box under the dashboard or in the engine compartment.
Identify the power window fuse using the diagram on the fuse box cover.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity; if blown, replace it with a fuse of the same amperage.

3. Test Power Window Switch

Reconnect the battery.
Remove the switch panel carefully using a flathead screwdriver to avoid damage.
Disconnect the switch connector and use a multimeter to check for voltage at the connector when the switch is activated.
If no voltage is detected, consider replacing the switch.

4. Test Power Window Motor

With the switch connected, apply direct power from a 12V battery to the motor terminals.
If the motor operates, the issue lies with the wiring or switch; if not, replace the motor.

5. Inspect Wiring and Regulator

Check wiring harness connections for any corrosion or loose connections.
If the wiring is intact, inspect the window regulator for any physical damage or obstructions that may prevent window movement.
Replace the regulator if it is found to be faulty.
