SYSTEM DESCRIPTION [03/2012 - ]

  1. GENERAL The blower volume has 3 levels controlled by operating the dial-type climate control seat switch, which is located in the console box. Whether the blower is ON or OFF can be determined by checking if the climate control seat switch indicator light is ON or OFF. The blowers of both seats are controlled by the air conditioning amplifier assembly (A/C ECU).

DESCRIPTION

The A/C amplifier assembly receives seat heater switch position signals when the engine switch is on (IG), and then transmits airflow amount signals to each seat climate blower.
