Diagnostic Procedure 1
SYMPTOM: Blower motor does not rotate.
IPerform PRELIMINARY CHECK 2 before referring to the
following flow chart.
Check if blower motor rotates properly at
each fan speed.
Conduct check as per flow chart at left.234EqB5EqC
(Go to next page.)

CHECK POWER SUPPLY FOR BLOWER
MOTOR.
IDisconnect blower motor harness con-
nector.
ITurn ignition switch to ACC or ON posi-
tion.
Do approx. 12 volts exist between blower
motor harness terminal No.q
1and body
ground?
OK
ENG
Check 15A fuses at fuse
block.
(Refer to ªPOWER SUP-
PLY ROUTINGº in EL sec-
tion and ªWiring Diagramº.)
IPut fan switch to ON position.
Check circuit continuity between blower
motor harness terminal No.q
2and body
ground.
OK
ENG
Reconnect blower motor
harness connector.
CHECK BLOWER MOTOR.
(Refer to Electrical Components Inspec-
tion.)
NG
Replace blower motor.
CHECK BLOWER MOTOR CIRCUIT
BETWEEN BLOWER MOTOR AND
RESISTOR.
IPut fan switch to OFF position.
Do approx. 12 volts exist between resistor
harness terminal No.q
1and body ground?
OK
ENG
Disconnect blower motor
and resistor harness con-
nectors.
Note
ITurn ignition switch OFF.
