Operation Check

  1. CLEAN AIR FILTER AND PERFORM DUCT INSPECTION 
    1. Remove the rear seatback assembly and rear seat cushion assembly.
    2. Check if the duct of the seat climate control controller is disconnected or cracked.
    3. Clean the air filter of the seat climate control controller.

      HINT: 

      The amount of air passing through the seat climate control controller (Peltier) may decrease if one of the following occurs: 1) duct disconnection; 2) duct cracks; 3) severe clogging of air filter; or 4) deterioration of fan motor performance. If this occurs, the thermistor operates excessively, which may cause the seat to be unable to cool down properly.

  2. INSPECT AIR SEAT OPERATION 
    1. When the seat heater switch is turned ON, check that the seat heater or blower fan operates.
