1. Remove the sunlight sensor (A) from thedashboard (see page 21-69).
2. Turn the ignition switch to ON (II). Measure the voltage between the terminals with the ( ) probe
on terminal No. 2 and the ( ) probe on terminal
No. 1 with the connector connected.
NOTE: The voltage readings will not change under
the light of a flashlight or a fluorescent lamp.
Voltage should be: 3.6 3.7 V or more with the sensor out of direct sunlight.
3.3 3.5 V or less with the sensor in direct sunlight.
3. If the voltage is not as specified, replace the sunlight sensor (see page 21-69). 1. Remove the gauge control module (SPEEDO)
(see page 22-277).
2. Remove the sunlight sensor (A) from the dashboard with a flat-tip screwdriver, then
disconnect the connector (B). Be careful not to
damage the sensor and the dashboard.
3. Install the sensor in the reverse order of removal.

Possible Leak AreaDiagnostic Procedure with Fluorescent Dye
21-96Climate Control
Refrigerant Leak Check (cont’d)
NOTE:
Check for leaks in a dark work area, and use the UV light and the special glasses from the leak check kit. Other UV lights may not work well with the Tracer-Stick
dye.
Small leaks may take up to 1 week of vehicle operation (with normal A/C use) to become visible.
Service Ports If a leak is found, replace the Schrader valve on the service port.
A/C Lines Use a permanent marker pen to circle the leak area.
If a leak is found, remove and replace the A/C line (see page 21-8).
Condenser If a leak is found, remove the condenser (see page 21-88). Determine whether leak is in the condenser or the receiver/dryer.
Use a permanent marker pen to circle the leak area.
Replace either the receiver/dryer (see page 21-89), or the condenser
(see page 21-88), depending upon which is leaking.
A/C Compressor Check for leaks at all of the compressor joints, the clutch center, the compressor front housing bolts, and the scroll bolts on the back of the
compressor.
If a leak is found, use a permanent marker pen to circle the leak area.
If the compressor relief valve appears to be leaking, determine whether the
leak is coming from the relief valve, or the joint between the compressor
casing and the valve.
If the leak is from the relief valve, check the A/C system pressures, and refer
to the pressure test table in the A/C system test (see page 21-99). If the leak is
from the casing/valve joint, replace the A/C compressor relief valve (see page
21-87).
If the leak is coming from the suction hose and/or discharge hose fittings on
the compressor, clean the A/C fittings and replace the suction/discharge
fitting O-rings.
For all other compressor leaks, remove and replace the A/C compressor
(see page 21-83).
Evaporator Start checking for evaporator leaks by illuminating the evaporator drain tube area.
If a leak is found, remove theevaporator core (see page 21-78).
Determine whether leak is from evaporator or expansion valve.
Use a permanent marker pen to circle the leak area.
Replace the expansion valve (see page 21-80), or the evaporator core
(see page 21-78), depending upon which is leaking.

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.
