Inspection

  1. Turn the ignition off.
  2. Disconnect the temperature control actuator connector.
  3. Make sure the temperature control actuator operates to the warm (driver side) or cool (passenger side) position when 12 V is applied to terminal 3 and ground terminal 4. Make sure the temperature control actuator operates to the cool (driver side) or warm (passenger side) position when the connections are reversed.

  4. Connect the temperature control actuator connector.
  5. Turn the ignition on.
  6. Check the voltage between terminals 6 and 7 (between terminals 5 and 6 on the passenger side). Specification
    Door Position Voltage (V) Fault Detection
    Max. Cool 0,3±0,15 Low voltage: 0.1 V or less
    Max. Heat 4,7±0,15 High voltage: 4.9 V or more

    It will report the current actuator position to the controls.
  7. If the measured voltage does not meet the specification, replace the temperature control actuator with a genuine part and check the operation.
  8. Replace the temperature control actuator if it is determined to be faulty.

Replacement

[Driver Side]
  1. Disconnect the negative (-) battery terminal.
  2. Remove the main crash pad. (Refer to Body - "Crash Pad")
  3. Disconnect the connector (A), then remove the driver side temperature control actuator (B) after loosening the mounting screws.
  4. Install in the reverse order of removal.
  5. Disconnect the negative (-) battery terminal.
  6. Remove the main lower airbag unit. (Refer to Body - "Main Lower Airbag Assembly")
  7. Remove the passenger side air vent duct (A) after loosening the screw.
  8. Disconnect the connector (A), then remove the passenger side temperature control actuator (B) after loosening the mounting screws.
  9. Install in the reverse order of removal.
