(3) Use a multimeter set on lowest OHMS scale to check for continuity between each pin A, B, and C
in motor connector (2) and the motor (3) housing. If there is continuity between any pin and motor
housing, the motor winding is shorted. Replace motor.
(4) Use a multimeter set on high OHMS scale to test stator insulation by checking between each pin
A, B, and C in motor connector (2) and motor (3) housing. A reading of less than 500,000 ohms
indicates insulation failure. Replace motor.
(5) Check continuity between pins D and E in motor connector (2). If there is no continuity, this
indicates an open thermostat. Replace motor.
(6) If motor (3) tests good, connect harness connector (1) to motor connector (2).
b. Removal.
NOTE
Removal is typical for both fans.
(1) Disconnect harness connector (1) Figure 3-56 from motor connector (2).
(2) Note rotation of fan (4) and loosen two sets screws (5). Remove fan (4).
(3) Remove six screws (6), flat washers (7), and inlet bell (8).
