   The climate control module is the central command center of your Air Conditioning System. Located in your dash, it reads all direction from the cabin and outside of the vehicle and uses that information to regulate and adjust heating and cooling requests. This item may also be called the "HVAC" (Heating, Ventilation, and Air Conditioning) Unit. Troubleshooting this part typically requires the use of a scan device that can read and access the HVAC codes.
