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.

Pinpoint Test E: LFC 15/DTC B1916 - Driver Air Bag Circuit Shorted to
Battery or Ignition
Normal Operation
The restraints control module (RCM) checks for driver air bag circuit
shorts to battery or ignition by
monitoring the voltage of circuit 614 (GY/OG) and 615 (GY/WH) at pins 3 and
4. If the RCM detects a
short to battery or ignition on e ...
Connecting Rod - Bushing Diameter
1. Measure the inner diameter of the connecting rod bushing, if equipped.
Verify the diameter is
within specification.
Refer to the appropriate section in Group for the procedure.
If out of specification, install new components as necessary. Refer
