Locate the blend door actuator, typically found behind the dashboard near the HVAC unit.
Disconnect the actuator’s electrical connector by pressing the release tab.
Remove the screws holding the actuator in place using a socket or screwdriver.
Carefully pull the actuator away from the assembly.

4. Install the New Blend Door Actuator

Align the new actuator with the mounting holes.
Secure it in place with screws and reconnect the electrical connector.
Ensure the actuator is seated properly to avoid misalignment.

5. Reassemble the Dashboard

Reinstall the dashboard panel by aligning it and securing it with screws and clips.
Double-check that all components are secured and no tools are left behind.

6. Reconnect the Battery

Reconnect the vehicle battery and ensure all connections are tight.

7. Test the System

Start the vehicle and check the climate control system to ensure that the temperature adjustments are functioning correctly.
