2. INSPECT FAN MOTOR
(a) Disconnect 2±P connector of the fan motor.
(b) Using wire harness, apply battery voltage to the con-
nector.
(c) Confirm smooth rotation of the motor within the spe-
cified current flow.
Standard current: 6.6

If defective, replace the motor.
3. CHECK HIGH PRESSURE SWITCH
(a) Install manifold gauge set.
(See page AC±23)
(b) Check continuity between the two terminals of the
pressure switch when refrigerant pressure is less
than approx. 12.5 kg/cm2 (178 psi, 1,226 kPa).
(e) Check that there is no continuity between two termi-
nals of the pressure switch when refrigerant pres-
sure is more than approx. 15.5 kg/Cm2 (220 psi,
1,520 kPa).
If continuity is not as specified, replace the switch.
