What should I check before buying to ensure proper fit?

Blend door actuators can be located in different positions and perform different functions depending on vehicle configuration. Use your vehicle Year/Make/Model selector and verify the actuator position (main/mode) before completing the purchase to prevent ordering the wrong part.

• Confirm vehicle year, engine size, and whether your model has V8 exclusions listed
• Identify whether you need the main/mode actuator versus a different HVAC door motor
• Compare the old actuator’s reference numbers (52473356, 1572505, etc.) with this unit
