Solution

1. Preparation

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

2. Check and Replace Fuse

Locate the fuse box (usually 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; replace with the same amperage if blown.

3. Inspect and Replace Power Window Switch

Remove the door panel using a socket set and trim removal tools.
Disconnect the electrical connector from the power window switch.
Use a multimeter to test the switch for continuity.
Replace the switch if it fails the continuity test by reversing the removal steps.

4. Test Window Motor

If the switch is functional, disconnect the window motor from its connector.
Using jumper wires, connect the motor directly to the battery to check for operation.
If the motor does not work, replace it by removing the window regulator assembly if necessary.

5. Reassemble Components

Reconnect all electrical connectors.
Reinstall the door panel securely, ensuring all fasteners are tightened.
Reconnect the vehicle battery.
