1. Remove the intake air duct (see page 11-348) and
the air cleaner assembly (see page 11-345).
2. Disconnect the transmission range switch subharness connector (A).
3. Check for continuity between the terminals at the harness connector. There should be continuity
between the terminals in the following table for
each switch position. 4. Transmission range switch test has completed if
the test results are OK, go to step 12. If there is no
continuity between any terminals, go to step 5.

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.

10. To complete the vent (delivery)/ambient air (intake) temperature chart:
 Mark the vent (delivery) temperature on the vertical line.
 Mark the ambient air (intake) temperature on the bottom line.
 Draw a vertical line from the ambient air (intake) temperature mark.
 Draw a horizontal line from the vent (delivery) temperature mark unit it intersects the vertical line.NOTE: The low side and intake temperatures should intersect in the shaded area within about 10 % of the
measured humidity level. Any measurements outside the line may indicate the need for further inspection.
