This air door actuator directly replaces the original actuator on specific Dodge and Ram vehicle years, makes, models, configurations and positions to restore proper HVAC operation. After installation, this actuator requires recalibration using an appropriate scan tool. Please note that many vehicles have several different air door actuators, which are designed for specific positions and functions in the vehicle. To ensure you have what you need, carefully review the application notes for this part to verify it matches the position and function of the actuator you need to replace. In some online ordering systems, you may need to enter your vehicle information first to see the application notes for your vehicle. If you don't know which actuator position you need to replace, consult a qualified service technician.
