Solution

1. Preparation

Gather tools: Screwdriver set, OBD-II scanner, flashlight, and multimeter.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect Cabin Air Filter

Locate the cabin air filter housing, typically found behind the glove compartment.
Remove the glove compartment by unscrewing any fasteners and detaching it from its hinges.
Remove the cabin air filter and inspect it for dirt or blockages.
Replace it if necessary with a new filter.

3. Access HVAC Components

Remove the dashboard cover by unscrewing the necessary screws and clips.
Carefully detach the cover to avoid damaging any clips.
Visually inspect the area for any loose connections or foreign objects.

4. Check Actuator Motors

Locate the actuator motors controlling airflow and temperature.
Use a multimeter to test for continuity in the actuator motors.
If a motor is found to be faulty, disconnect it and replace it with a new one.

5. Reassemble and Test

Reattach the dashboard cover, ensuring all clips and screws are secured.
Reconnect the battery.
Start the vehicle and activate the climate control to check for noises and proper operation.
