1. SET VEHICLE IN THESE CONDITION
(a) Engine speed at 1,500 rpm
(b) Blower speed control switch at ºHIº position
(c) Temperature control dial at ºMAX. COOLº position
(d) Manifold gauge set setting
2. INSPECT PRESSURE SWITCH OPERATION
(a) Disconnect the connector.
(b) Inspect pressure switch continuity (Magnetic Clutch Con-
trol)
(1) Connect the positive (+) lead from the ohmmeter to
terminal 1 and the negative (-) lead to terminal 2.
(2) Check continuity between terminals when the re-
frigerant pressure is changed, as shown in the il-
lustration.
If continuity is not as specified, replace the pressure switch.

REMOVAL
1. DISCHARGE REFRIGERANT FROM REFRIGERATION
SYSTEM
HINT:
At the time of installation, evacuate air from refrigeration system
and charge system with refrigerant and inspect for leakage of
refrigerant.
Specified amount: 1,050 ± 50 g (37.03 ± 1.76 oz.)
2. REMOVE RADIATOR GRILL
3. REMOVE PRESSURE SWITCH FROM LIQUID TUBE
Disconnect the connector and remove the pressure switch.
Torque: 10 N´m (100 kgf´cm, 7 ft´lbf)
HINT:

Lock the switch mount on the tube with an open-end
wrench, be careful not to deform the tube, and remove the
switch.

At the time of installation, lubricate a new O-ring with
compressor oil and install the switch.

REAR A/C CONTROL ASSEMBLY
INSPECTION
1. REMOVE REAR HEATER CONTROL ASSEMBLY
Using a screwdriver, release the 4 claws and pull out the rear
heater control assembly, then disconnect the connector.
2. INSPECT ILLUMINATION OPERATION
Connect battery positive (+) lead to terminal 2 and battery nega-
tive (-) lead to terminal 21 then check that the indicators come
on.
If operation is not as specified, replace the rear A/C control as-
sembly.
3. INSPECT INDICATOR OPERATION
(a) Connect battery positive (+) lead to terminal 1 and battery
negative (-) lead to all the other terminals, then check that
the indicator come on, as shown in the chart.

Standard resistance: 3.0 kW
(b) Gradually move the temperature control lever from
ºCOOLº side to ºWARMº side, then check that the resis-
tance between terminal 11 and 12 increase to 3.0 kW.
If operation is not as specified, replace the rear A/C control as-
sembly.
