How to replace blend door actuator Dodge caravan

Today you will find controlled environments, passenger cells that can be environmentally controlled through electronics, which basically means anywhere in a caravan can get different cooling levels all controlled by the individual in the specific environmental cell or location.

The HVAC Air Door Actuator

HVAC actuators are essentially valves that can be controlled locally, and wherever there is an actuator, it means that at that location, you can control the flow of air. The Dodge caravan has actuators in the door, which means that airflow at the door is controllable. Since all electro-mechanical devices are prone to wear and tear and damage, it is natural that over time and use the door actuators will require repair or replacement. In this article, I present to you a basic review of replacing the door actuator in the Dodge caravan.

Replacing the HVAC door actuator – Passenger Side

Let me start off by stating that replacing the blend door actuator is not rocket science, but it does come with its own issues.

Step 1: Safety

Before starting work on any electromechanical system in a vehicle, always disconnect the battery. You do this by isolating the negative cable.

Step 2: Silencer (Optional)

Some caravans have an isolator underneath the instrument panel on the passenger side, you will need to remove this first.

Step 3: Disconnecting

Reach in to unscrew the 2 screws that are located between the HVAC air distribution housing and the HVAC air inlet housing. See (1) in the drawing. After unscrewing these 2 screws, you can remove the actuator. The actuator is connected to the electrical system via the wire harness (4) , you need to open the red locking tab to disengage the connection. Now you can remove the actuator from its location.

Step 4: Installation

Insert the new actuator by positioning it to the passenger side (2) of the HVAC housing. Connect the wire harness and secure it by clicking the red locking tab into place. Now attach the actuator to the bracket (3), you will need to align the splines by rotating the actuator slightly. Screw in the 2 screws (1) and secure the actuator back onto the HVAC housing by tightening the screws with a 10”/lbs torque. Now reinstall the silencer if you had one. Connect the battery negative.

Step 5: Calibration and Operation

Now turn the A/C on and calibrate the temperature control for testing.

Replacing the HVAC door actuator – Driver Side

Step 1: Safety

Before starting work on any electromechanical system in a vehicle, always disconnect the battery. You do this by isolating the negative cable.

Step 2: Disconnecting

First, remove the knee blocker located on the driver’s side. Reach in to unscrew the 2 screws (1) in the drawing. After unscrewing these 2 screws, you can remove the actuator. The actuator is connected to the electrical system via the wire harness, you need to open the red locking tab (2) to disengage the connection. Now you can remove the actuator from its location.

Step 3: Installation

Insert the new actuator by positioning it to the driver side (3) of the HVAC housing (4). You might need to rotate it slightly to align the splines. Connect the wire harness and secure it by clicking the red locking tab into place. Now attach the actuator to the bracket, you will need to align the splines by rotating the actuator slightly. Screw in the 2 screws (1) and secure the actuator back onto the HVAC housing by tightening the screws with a 10”/lbs torque. Reinstall the knee blocker. Connect the battery negative.

Step 4: Calibration and Operation

Now turn the A/C on and calibrate the temperature control for testing.
