Mode Door Control Specification
Mode position can be selected manually by pressing the MODE switch or the DEF switch on the A/C and AV switch assembly. Pressing the AUTO switch allows automatic control by the A/C auto amp.
During the automatic control of a mode position, a mode door position (VENT, B/L, FOOT, or D/F) is selected based on a target air mix door opening angle and sunload sensor, calculated by the A/C auto amp. In addition, the D/F is selected to prevent windshield fogging only when ambient temperature is extremely low.
