Door Switch
1. Check for continuity of the switch with an
ohmmeter.
2. If continuity is not as specified, replace the switch.
Washer Level Sensor
1. Check for continuity between C (LY) terminal and
D (B) terminal of the washer level sensor con-
nector.
Oil Pressure Switch
1. Disconnect the connector from the oil pressure
switch.
2. Check for continuity between the switch and a
body ground with each condition.
Coolant Level Sensor
1. Remove the level sensor and connect the con-
nector.
2. With the sensor not grounded to the body, start
the engine.
3. After checking that the warning light illuminates,
ground the threaded part of the sensor.
4. If the warning light remains illuminated, the sen-
sor is faulty and replace it.

ON-VEHICLE INSPECTION
1. Connect the manifold gauge set.
2. Run the engine at 1,500 rpm.
3. Check the compressor flow:
a) High pressure is not low and low pressure is not
higher than normal.
b) Metallic sound.
c) Check to be sure that the high-pressure and low-
pressure gauges show the same value immedi-
ately after the air conditioner is switched OFF.
If both gauges show the same value immediate-
ly, it can be assumed that the gasket or the valve
inside the compressor is damaged.
4. Stop the engine.
5. Check the shaft seal and others for leakage.
6. Inspect the drive plate pulley magnetic clutch for
signs of oil.
7. Check the clearance between the drive plate and
pulley. (Refer to page 16—21.)
If any of the above checks reveal faults, repair the
compressor or magnetic clutch.

REMOVAL OF COMPRESSOR
1. Perform the Oil Return Operation. (See below.)
2. Disconnect the battery ground cable.
3. Disconnect the clutch lead wire from the wiring
harness.
4. Discharge the refrigerant from the refrigeration
system.
5. Disconnect the two flexible hoses. Plug the open
fittings immediately to keep moisture out of the
system.
6. Loosen the drive belt.
7. Remove the compressor mounting bolts and the
compressor.

Oil Return Operation
1. If the refrigerant level is low, charge the system to
the specified amount.
2. Run the engine and air conditioner at idle and at
maximum cooling for at least 20 minutes.
