DESCRIPTION

Slight variations exist among manual A/C-heater systems used.

On Montero, a Nippondenso 10-cylinder compressor is used. Cycling of

compressor clutch is controlled by an automatic A/C Control Unit

(ACCU).

Compressors will only operate within normal temperatures and

pressures set for each model. An electric condenser fan operates

whenever A/C system is operating. System components may vary depending

upon model. Systems may include an ACCU, fan switch, evaporator,

temperature sensor, dual-pressure switch, engine coolant temperature

switch, compressor, condenser, receiver-drier and various pipes and

hoses.

OPERATION

A/C CONTROL UNIT (ACCU)

ACCU controls cycling of compressor clutch based on

information received from air thermosensor and air inlet sensor, dual-

pressure switch, A/C switch and A/C engine coolant temperature switch.

ACCU is attached to top of evaporator housing.
