Performance Test
21-99
A/C System Test
A
B
 Air conditioning refrigerant or lubricant vapor can irritate your eyes, nose, or throat.
 Be careful when connecting service equipment.
 Do not breathe refrigerant or vapor.
The performance test will help determine if the A/C
system is operating within specifications.
NOTE:  If accidental system discharge occurs, ventilate the work area before resuming service.
 Additional health and safety information may be obtained from the refrigerant and lubricant
manufacturers.
1. Do the A/C system inspection (see page 21-6), and correct any problems found.
2. Connect an R-134a refrigerant recovery/recycling/ charging station to the high-pressure service port
and the low-pressure service port, following the
equipment manufacturer’s instructions.
3. Determine the relative humidity and air temperature.
4. Open the glove box. Remove the glove box stop on each side, then let the glove box hang down
(see page 20-104).
5. Insert a thermometer (A) in the center vent. 6. Place a thermometer (B) near the blower unit’s
recirculation inlet duct.
7. Test conditions:  Move the vehicle out of direct sunlight and let itcool down to the surrounding (ambient)
temperature. If necessary, wash the vehicle to
cool it down more quickly.
 The ambient temperature must be at least 16 °C (60 °F).
 Open the hood.
 Open the front doors.
 Set the temperature control dial to Max Cool, the mode control switch to Vent, and the
recirculation control switch to Recirculate.
 Turn the A/C switch ON and the fan switch to Max.
 Hold the engine speed at 1,500 rpm.
 No driver or passengers in the vehicle.
8. Inspect the A/C components for the following conditions:
 A/C compressor clutch not engaged.
 Abnormal frost areas.
 Unusual noises.
If you observe any of these conditions, refer to the
Symptom Troubleshooting Index.
9. After running the air conditioning for 10 minutes under the above test conditions, read the delivery
temperature from the thermometer in the center
vent, the intake temperature near the blower unit,
and the discharge (high) and suction (low)
pressures on the A/C gauges.

switch is in the appropriate position. Go to function and input test for the system
related to the failure.
Repair the open, short, or replace the faulty
switch.
