Replace the main
fan relay 2. <Ref. to
AC-39, Relay and
Fuse.>
14
CHECK HARNESS BETWEEN MAIN FAN
RELAY 2 AND MAIN FAN MOTOR ASSEM-
BLY CONNECTOR.
1) Disconnect the connector from the main fan
motor assembly.
2) Measure the resistance of harness between
the main fan relay 2 terminal and main fan
motor assembly connector.
Connector & terminal
(F17) No. 2 — (F27) No. 21:
