SIGHT GLASS
Checking refrigerant charge
1. Run the engine at a fast idle.
2. Operate the air conditioner at maximum cooling for a few
minutes.
3. Determine the amount of refrigerant as shown below by ob-
serving the sight glass.
Item Symptom Amount of refrigerant Action
I Bubbles present in sight glass Insufficient refrigerant Check refrigerant pressure
2 No bubbles present in sight glass Too much or proper amount of Turn air conditioner OFF, and
refrigerant watch bubbles (Refer to Items 3
and 4)
3 Immediately after air conditioner turned Too much refrigerant Check refrigerant pressure
OFF, refrigerant in sight glass stays clear
4 When air conditioner turned OFF, refrigerant Proper amount of refrigerant Refrigerant amount normal
foams, and then sight glass becomes clear
QMUOUX-140
Checking refrigerant pressure
1. Connect the manifold gauge set. (Refer to page U--32.)
2. Operate the engine at 2,000 rpm and set the air condition-
er to maximum cooling.
3. Measure the low- and high-pressure sides.
Normal pressure
Low-pressure side: 147-294 kPa
(1.5-3.0 kg/cm2, 21-43 psi)
High-pressure side: 1 ,I 77-l ,619 kPa
(12.0-l 6.5 kg/cm2, 171-235 psi)

On-vehicle Inspection
Thermoswitch
1. Remove the glove box.
2. Run the engine at idle.
3. Turn OFF the A/C switch and set the blower switch to the
highest position to operate the blower fan for a few minutes.
4. After a few minutes, turn OFF the blower switch and stop
the engine.
5. Disconnect the thermoswitch connector and check for con-
tinuity between terminals of the switch.
Terminals Continuity
a-b Yes
6. If not as specified, replace the thermoswitch.
Note
l The thermoswitch contacts will be open if the
evaporator temperature is below 0.4 f 0.7OC (32.7
z!z 1.3OF).
Inspection
Thermoswitch
1. Immerse the sensing bulb in a container of ice water.
2. Check continuity between terminals of the switch as
specified.
Terminals
a-b Temperature Continuity
Above 5°C Yes
Below 0% No
3. If not as specified, replace the thermoswitch
Evaporator
1. Check the evaporator fins for blockage. If the fins are
clogged, clean them with compressed air.
Caution
l Never use water to clean the evaporator.
2. Check the fittings for cracks and other damage.
Replace the evaporator if necessary.

REFRIGERANT PRESSURE SWITCH No.1
Inspection
1. Turn the ignition switch OFF.
2. Connect the manifold gauge set and measure the high-
pressure side refrigerant pressure.
High-pressure side:
Above 451 kPa (4.6 kg/cm2, 65 psi)
3. If not as specified, check the refrigerant system, referring
to the troubleshooting information on page U-14.
4. If correct, go to the next step.
5. Disconnect the refrigerant pressure switch No.1 connector.
6. Check for continuity of the switch.

7. If not as specified, replace the switch together with cooler
pipe No.2. (Refer to page U-54.)
Note
l If problems occur in the refrigeration system, caus-
ing abnormally high (above 2,649 SL: 196 kPa [27 f
2 kg/cm2, 384 f 28 PSI]) or low (below 196 f 20
kPa [2.0 f 0.2 kg/cm2, 28 & 2.8 psi]) pressures,
refrigerant pressure switch No.1 cuts power to the
magnetic clutch to protect the mechanical compo-
nents. If the pressure recovers to within normal
operating range (below 2,080 f 392 kPa [21 f 4
kg/cm2, 299 f 57 psi] or above 402 f. 49 kPa t4.1
f 0.5 kg/cm2, 58 f 7 psi]), the power is again re-
stored.
REFRIGERANT PRESSURE SWITCH No.2
(BP ENGINE WITH ATX)
Inspection
1. Turn the ignition switch OFF.
2. Connect the manifold gauge set and measure the high-
pressure side refrigerant pressure.
High-pressure side:
below 1,177 kPa (12 kg/cm2, 171 psi)
3. Disconnect the refrigerant pressure switch No.2 connector.
4. Check continuity of the switch.

Caution
l While testing refrigerant pressure switch No.2, care-
fully note the high-pressure side refrigerant pres-
sure. If the pressure increases above 1,766 kPa (18
kg/cm2, 256 psi), stop the testing. _,
7. Disconnect the condenser fan connector.
8. Run the engine at 2,000 rpm, and operate the air condi-
tioner at maximum cooling position.
9. Check that the refrigerant pressure switch turns on when
the high-pressure side refrigerant pressure increases above
1,570 f 98 kPa (16 f 1 kg/cm2, 228 f 14 psi).
IO. If not as specified, replace the switch together with cooler
pipe No.2. (Refer to page U-54.)
