2. INSPECT REFRIGERANT PRESSURE WITH MAN-
IFOLD GAUGE SET
This is a method in which the trouble is located by using a man-
ifold gauge set. Read the manifold gauge pressure when the
these conditions are established.
Test conditions:

Temperature at the air inlet with the switch set
at RECIRC is 30 ± 35 °C (86 ± 95 °F)

Engine running at 1500 rpm

Blower speed control switch at ºHIº position

Temperature control dial on ºCOOLº position
HINT:
It should be noted that the gauge indications may vary slightly
due to ambient temperature conditions.
(1) Normally functioning refrigeration system.
Gauge reading:
Low pressure side:
0.15 ± 0.25 MPa (1.5 ± 2.5 kgf/cm
2)
High pressure side:
1.37 ± 1.57 MPa (14 ± 16 kgf/cm

(1) Inert SST to piping clamp.
HINT:
Confirm the direction of the piping clamp claw and SST using
the illustration showing on the caution label.
(2) Push down SST and release the clamp lock.
NOTICE:
Be careful not to deform the tubes, when pushing SST.
(3) Pull SST slightly and push the release lever, then re-
move the piping clamp with SST.
(4) Remove the piping clamp from SST.
(b) Disconnect the both tubes.
NOTICE:

Do not use tools like screwdriver to remove the tube.

Cap the open fittings immediately to keep moisture or
dirt out of the system.
HINT:
At the time of installation, please refer to the following item.

Lubricate 4 new O±rings with compressor oil and install
the tubes.

After connection, check the fitting for claw of the piping
clamp.
7. REMOVE A/C UNIT
(a) Disconnect the connector.
(b) Slide the floor carpet backward.
(c) Remove the rear heater duct.
(d) Remove the 2 nuts and A/C unit.

INSPECTION
1. INSPECT A/C INDICATOR OPERATION
(a) Connect the positive (+) lead from the battery to terminal
2 and the negative (±) lead to terminal 1.
(b) Push the A/C button in and then check that the indicator
lights up.
If operation is not as specified, replace the switch.
2. INSPECT DIMMING OPERATION
(a) Connect the positive (+) lead from the battery to terminal
2 and the negative (±) lead to terminal 1 while press the
switch.
(b) Connect the positive (+) lead from battery to terminal 4
and then check that the indicator dims.
If operation is not as specified, replace the switch.
