Air Conditioning: Notes
WARNING: This page is about a different car, the 2004 Ford Focus. However, it is still accessible from the selected car via links, so may be relevant.
The A/C refrigerant system is a clutch cycling orifice tube type. The system components are:
- A/C compressor (19703)
- A/C clutch assembly
- A/C condenser core (19712)
- A/C evaporator core (part of 19850 assembly)
- suction accumulator (19C836)
- connecting refrigerant lines
The refrigerant system operation is controlled by the:
- A/C evaporator core orifice (19D990).
- A/C cycling switch (19E561).
- A/C compressor pressure relief valve (19D644).
- A/C pressure cutoff switch (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 A/C evaporator core orifice is installed in the condenser to evaporator tube (19835) to meter the liquid refrigerant into the A/C evaporator core.
