Ford Mustang (1999-2004) Service Manual: Air Conditioning (Description and Operation)
The A/C refrigerant system is a clutch cycling orifice tube type. The system components are:
- A/C compressor (19703)
- A/C clutch (2884)
- A/C condenser core (19712)
- A/C evaporator core (19860)
- suction accumulator (19C836)
- connecting refrigerant lines
The refrigeration system operation is controlled by the:
- A/C evaporator core orifice (19D990).
- A/C cycling switch (19E561).
- A/C compressor pressure relief valve (19D644).
- Refrigerant containment switch (3.8L) (19D594).
- Dual-function pressure switch (4.6L) (19D594).
The refrigerant system incorporates an A/C compressor controlled by an A/C cycling switch.
The A/C cycling switch senses A/C evaporator core pressure to control A/C compressor operation.
An A/C compressor pressure relief valve is installed in the A/C manifold and tube (19D734) to protect the refrigerant system against excessively high refrigerant pressures.
An evaporator core orifice is installed in the A/C evaporator core inlet tube to meter the liquid refrigerant into the A/C evaporator core.
A refrigerant containment switch is installed on 3.8L vehicles to cut-off A/C compressor operation in the event of abnormally high refrigerant system pressure.
A dual-function pressure switch is used on 4.6L vehicles for cooling fan control, and to cut-off A/C compressor operation in the event of abnormally high refrigerant system pressure.
