HEATER, AIR
AND VENTILATION General Information
GENERAL INFORMATION
The heater system uses a two-way-flow full-air-mixThe A/C system is basically the same as the
system that features high performance and lowtional system, but a new refrigerant system
operating noise, and includes an independent facebeen adopted as a response to
air blowing function and a air bypass function.use of chlorofluorocarbons. ,

SYSTEM TROUBLESHOOTING.
Compressor control
lWhen the air conditioning switch is pushed in (A/C switch: ON) or the air outlet changeover
control knob is moved to the DEF or
position (defroster switch: ON), the air
conditioning system operates and compressor
control starts.
l The fin sensor, which senses the
temperature. of the air flowing out of the
evaporator, is deactivated with. temperature
3.2%
or below.
Here, the engine coolant ‘temperature sensor
senses the temperature of coolant,
it is turned off at or higher
peratures.
lThe dual pressure switch turns OFF when
refrigerant pressure becomes high
or low, thus the compressor circuit.
(See Table below.)
