FRONT CLIMATE CONTROL UNIT CONSTRUCTION/OPERATION

BME074061192T01
• A wire logic type front climate control unit had been adopted.
• The front defroster control prevents window fogging.

## Front Defroster Control Operation

### European (L.H.D. U.K.) specs.

  • The operation is the same as that of the PREMACY. (See PREMACY Training Manual 3336-1*-99C)

### Australian, General (L.H.D.) specs.

  • When the airflow mode selector dial is turned to DEFROSTER position, a wire moves the airflow mode link, turning the airflow mode to DEFROSTER.
  • The microswitch turns on at the same time, and the CPU sends a signal to turn the air intake mode to FRESH and A/C to ON.
  • The air intake actuator operates and turns the air intake mode to FRESH.
  • The thermosensor sends the A/C ON signal to the PCM based on the signal of the CPU, and turns A/C on.
