A/C System - Manual

A/C System:

A/C SYSTEM
The A/C refrigerant system is a clutch cycling orifice tube type. The system components are:
- A/C compressor.
- A/C clutch.
- A/C condenser core.
- A/C evaporator core.
- Suction accumulator/drier.
- Connecting refrigerant lines.

The refrigeration system operation is controlled by the following:
- A/C evaporator core orifice.
- A/C cycling switch.
- A/C pressure cut-off switch.

Refrigerant System Components:

The refrigerant system incorporates an A/C compressor controlled by an A/C cycling switch. The A/C cycling switch senses pressure in the suction accumulator/drier to control operation of the A/C compressor.

An A/C compressor pressure relief valve is installed in the A/C manifold and tube to protect the compressor against excessively high refrigerant pressures. An A/C evaporator core orifice is installed to the condenser to evaporator tube to meter the liquid refrigerant into the A/C evaporator core.

The manual climate control system heats and/or cools the vehicle depending on the function selector switch position and the temperature selected.
- The function selector switch position determines heating or cooling and air distribution.
- The temperature control setting determines the air temperature.
- The heater blower motor switch varies the blower motor speed.
