When installed correctly and the system is properly recharged, our rear AC block off kits do not affect the performance of the front AC system. The driver and front passenger will experience normal cooling. However, rear passengers may notice reduced airflow or comfort, especially in larger vehicles, since the rear evaporator is no longer in use.

When installing rear AC block off kits, apply a very small amount of either: Refrigerant oil (compatible with your system’s refrigerant), or Silicone-based grease This helps ensure a proper seal without damaging the O-rings.
