9. Compare the compressor discharge pressure to the Performance Temperature and Pressure chart. If the com-
pressor discharge pressure is high, see the Pressure Diagnosis chart.
Rapid compressor clutch cycling
(ten or more cycles per minute).
Equal pressures, but the
compressor clutch does not engage.
Normal pressures, but A/C
Performance Test air temperatures
at center panel outlet are too high.
The low side pressure is normal or
slightly low, and the high side
pressure is too low.
The low side pressure is normal or
slightly high, and the high side
pressure is too high.
Pressure Diagnosis
1. Low refrigerant system charge.
1. No refrigerant in the refrigerant
system.
2. Faulty A/C compressor clutch
coil.
3. Faulty A/C pressure transducer.
4. Faulty A/C Heater Control
Module.
1. Excessive refrigerant oil in
system.
2. Blend door inoperative or sealing
improperly.
3. Blend door actuator faulty or
inoperative.
1. Low refrigerant system charge.
2. Refrigerant flow through the
receiver/dryer is restricted.
3. Refrigerant flow through the
evaporator is restricted.
4. Faulty compressor.
1. Condenser air flow restricted.
2. Inoperative cooling fan.
3. Refrigerant system overcharged.
4. Air in the refrigerant system.
1. Test the A/C system for leaks.
Repair, evacuate and charge the
refrigerant system, if required.
1. Test the A/C system for leaks.
Repair, evacuate and charge the
A/C, if required.
2. Test the compressor clutch coil
and replace, if required.
3. Test the A/C high pressure
transducer and replace, if required.
4. Test the A/C Heater Control
Module and replace, if required.
1. Recover the refrigerant from the
refrigerant system and inspect the
refrigerant oil content. Restore the
refrigerant oil to the proper level, if
required.
2. Inspect the blend door for proper
operation and sealing and correct, if
required.
3. Replace if faulty.
1. Test the refrigerant system for
leaks. Repair, evacuate and charge
the refrigerant system, if required.
2. Replace the restricted receiver/
drier, if required.
Replace the restricted evaporator
coil, if required.
Replace the compressor, if required.
1. Check the condenser for
damaged fins, foreign objects
obstructing air flow through the
condenser fins, and missing or
improperly installed air seals. Clean,
repair, or replace components as
required.
2. Test the cooling fan and replace,
if required.
3. Recover the refrigerant from the
refrigerant system. Charge the
refrigerant system to the proper
level, if required.
4. Test the refrigerant system for
leaks. Repair, evacuate and charge
the refrigerant system, if required.
