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.)
A/C RELAY
Inspection
1. Disconnect the A/C relay connector.
2. Check continuity between terminals of the switch.

Inspection
1. Disconnect the condenser fan connector.
2. Apply battery voltage to terminal a and ground terminal b,
and verify that the condenser fan operates.
3. If not as specified, replace the condenser fan.
A/C SWITCH
Inspection
1. Remove the A/C switch and check continuity between ter-
minals.
0-O: Indicates continuity
G-k0 Indicates diode
2. If not as specified, replace the A/C switch.
