Installation Notes and Tips
Verify the vehicle year, model, position, and climate-control configuration before installation. This actuator uses an arm linkage, 3 mounting ears, and a 5-pin terminal arrangement, so connector style and mounting points should match the original unit. For Volkswagen Passat and Volkswagen Beetle HVAC repairs, confirm whether the vehicle is left, right, or N/A position as listed in the fitment data, and check the dual-zone or ATC notes carefully.
