Fan motor NISSAN ALMERA N16 2003 Electronic Service Manual

12 CHECK CIRCUIT CONTINUITY BETWEEN HEATER CONTROL PANEL AND BLOWER MOTOR
Check circuit continuity between heater control panel harness terminal No. 17 and blower motor harness terminal No. 2.
NHA509
Continuity should exist.
If OK, check harness for short.
OK or NG
OK GO TO 13.
NG Repair harness or connector.
13 CHECK FAN SWITCH AFTER DISCONNECTING IT
(Refer to Electrical Components Inspection.)
(HA-51)
OK or NG
OK INSPECTION END
NG Replace fan switch.
