Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, multimeter, flathead screwdriver, and safety goggles.
Disconnect the vehicle's battery to prevent electrical shorts.

2. Remove Lower Dashboard Panel

Use a socket set to remove screws securing the lower dashboard panel.
Carefully pull the panel away from the dashboard, ensuring not to damage any clips or connectors.

3. Access HVAC Components

Locate the blower motor and blend door actuators within the HVAC housing.
Inspect the blower motor for any debris or foreign objects that may cause clicking.

4. Test Blend Door Actuators

Disconnect the electrical connectors from the blend door actuators.
Use a multimeter to check the voltage at the actuator connectors while operating the HVAC controls.
If no voltage is present, trace the wiring back to the control module for faults.

5. Replace Damaged Components

If a blend door actuator is faulty, remove it by unscrewing the mounting screws.
Install a new actuator, ensuring it is properly aligned and secured.
Reconnect the electrical connector.

6. Reassemble Dashboard

Reinstall the lower dashboard panel by reversing the removal steps.
Secure all screws and ensure no components are left loose.

7. Reconnect Battery

Reconnect the vehicle's battery and check for proper function of the HVAC system.
