Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Climate Controlled Seat (CCS) System
Both the driver and passenger seat have independent CCS systems. A CCSM mounted to the bottom of each seat cushion electronically controls each CCS system. The CCSM receive power from both battery positive voltage and ignition 1 voltage. The ignition must be in the ON position with the heated/cooled seat switch set in the HEAT or COOL position for CCS system to activate.
Once a CCS system is activated, cabin air is drawn through the blower motor and distributed to each of the heated/cool seat ventilation modules located under the seat cushion and in the seat backrest. The copper fins on the ventilation modules then heat or cool the passing air. The conditioned air is then directed into the bottom of the foam pad and along the surface of the seat to the occupant. The CCSM uses a set of algorithms to control the temperature of the heating/cooling modes.
