1B-34 AIR CONDITIONING (OPTIONAL)
5) Disconnect coupler from dual pressure switch (1).
6) Disconnect condenser outlet pipe (3).
7) Disconnect condenser cooling fan motor coupler (2).
8) Remove condenser with fan.
NOTE:
Be careful not to damage fins of condenser and radiator.
9) Remove A / C condenser cooling fan assembly from condenser.
INSTALLATION
Reverse removal sequence to install condenser, noting following
point.
1) When replacing condenser, add 20 to 30 cc of refrigerating oil
from compressor suction-side.
2) Evacuate and charge system according to previously-described
procedure.

COOLING UNIT (EVAPORATOR)
REMOVAL
1) Disconnect negative (±) cable at battery.
2) Disable air bag system. Refer to ªDisabling Air Bag Systemº in
Section 10B.
3) Recover refrigerant by using recovery and recycling equipment.
Be sure to follow the instruction manual for the equipment.
The amount of compressor oil removed must be measured and
the same amount added to the system.
4) For G16 and J20 engine
Disconnect suction pipe (1), and liquid pipe (2) from evaporator
(cooling unit).
CAUTION:
As soon as above hose and pipe are disconnected, cap
opened fittings so that moisture and dust may not enter
cooling unit.
5) Remove blower motor unit. Refer to Section 1A ªHEATER AND
VENTILATIONº.
6) Disconnect thermistor wire coupler.
7) Remove cooling unit (evaporator).
DISASSEMBLY (FOR CAMI PRODUCTION VEHICLE)
1) Remove filter (2) from cooling unit (3) assembly by removing fil-
ter cover (1).
2) Remove screws (1) to separate evaporator upper and lower
cases from each other.

REMOVAL AND INSTALLATION
For vehicle without air bag system, refer to Section 3C COMBINA-
TION SWITCH, and for vehicle with air bag system, refer to Section
3C1 CONTACT COIL AND COMBINATION SWITCH ASSEMBLY.
Wiper Motor
1) As illustrated, use a 12 V battery to connect its (+) terminal to ter-
minal ªAº, and its (±) terminal to Black lead wire (2) (Type A, B)
or terminal ªEº (Type C).
If motor (1) rotates at a low revolution speed of 45 to 55 rpm, it
is proper. For high speed check, connect battery (+) terminal to
terminal ªBº, and its (±) terminal to Black lead wire (2) (Type A,
B) or terminal ªEº (Type C). If motor rotates at a high revolution
speed of 67 to 83 rpm, it is proper.
