INSTALLATION
Reverse removal procedure for installation, and then note the fol-
lowing instructions.
Replenish specified amount of compressor oil to compressor
suction side by referring to “Replenishing Compressor Oil” in
this section.
Evacuate and charge refrigerant by referring to “Evacuation”
and “Charging” in this section.
Dual Pressure Switch
INSPECTION
1) Check dual pressure switch (1) for continuity at normal tem-
perature (approximately 25 °C (77 °F)) when A/C system has
a proper charge of refrigerant and A/C system (compressor)
is under operation. In each of these cases, switch should
show proper continuity.
2) Check switch for continuity at specified pressure as shown.
A : Approximately 195 kPa (1.95 kg/cm
2, 27.5 psi)
B : Approximately 3140 kPa (31.4 kg/cm
2, 446.5 psi)
C : Approximately 225 kPa (2.25 kg/cm
2, 32.0 psi)
D : Approximately 2550 kPa (25.5 kg/cm
2, 362.5 psi)

A/C Switch
REMOVAL AND INSTALLATION
Refer to “Heater Control Lever Assembly” in Section 1A.
INSPECTION
Press A/C switch button and check if there is continuity
between terminals “A” and “B”.
With battery voltage (+) connected to terminal “C” and (–) to
terminal “A”, press A/C Switch button and blower fan switch
to “Hi” (3rd position).
Check if indicator lamp lights.
Condenser Cooling Fan Motor Relay
INSPECTION
1) Disconnect negative (–) cable at battery.
2) Remove condenser cooling fan motor relay (1) from vehicle.
3) Check that there is no continuity between terminal “a” and
“b”. If there is continuity, replace relay.
4) Check that there is continuity between terminals “a” and “b”
when battery is connected to terminal “c” and “d”.
If there is no continuity, replace relay.
Compressor
REMOVAL
1) Run engine at idle speed with air conditioning ON for 10 min-
utes. After that stop the engine.
2) Disconnect negative (–) cable at battery.
3) Recover refrigerant from refrigeration system by referring to
“Recovery” in this section.
1. Blower fan and A/C switch
NOTE:
The amount of removed compressor oil must be mea-
sured for replenishing compressor oil.

4) Remove compressor drive belt (1) as follows.
For vehicle with P/S
Loosen tension pulley bolts (2).
For vehicle without P/S
Loosen tension pulley tightening nut (3) and adjusting bolt
(4).
5) Disconnect thermal switch connector.
6) Disconnect suction and discharge hoses from compressor.
7) Remove compressor (1) from its bracket (2).
INSTALLATION
Reverse removal procedure for installation, and then noting the
following instructions.
Replenish specified amount of compressor oil to compressor
suction side by referring to “Replenishing Compressor Oil” in
this section.
Evacuate and charge system by referring to “Recovery” in
this section.
Adjust drive belt tension by referring to “Compressor Drive
Belt” in this section.
[A] : Vehicle with P/S
[B] : Vehicle without P/S
NOTE:
Cap open fittings immediately to keep moisture out of
system.
NOTE:
If compressor is replaced, drain oil from removed com-
pressor. And then, measure its amount.
