TROUBLE DIAGNOSIS
Blower Fan Motor System To ESM
INSPECTION PROCEDURE
Symptom: Blower fan motor does not operate.
1. START INSPECTION
Check blower fan motor operation at each fan speed.
1 : Blower fan motor does not operate at all.
2 : Blower fan motor does not operate at one of speeds 1 - 4.
Do inspection results indicate 1 or 2 above?
1 >> GO TO 2.
2 >> GO TO 6.

2. CHECK POWER SUPPLY CIRCUIT
Disconnect blower fan motor connector, turn ignition switch ON, and
check voltage between blower fan motor connector terminal and
ground.
Connector terminal Voltage
Blower fan motor
Ground Battery voltage
1

OK or NG
OK >> GO TO 3.
NG >> Check power supply circuit and 15A fuses [Nos. 9 and MJIB0124E
10, located in the fuse block (J/B)]. Refer to PG-4,
"POWER SUPPLY ROUTING" on ESM..
q If OK, check for open circuit in wiring harness. Repair or replace as necessary.

q If NG, replace fuse and check wiring harness for short circuit. Repair or replace as necessary.

3. CHECK CIRCUIT CONTINUITY
1. Turn the fan setting dial (fan switch) to any position except OFF.
2. Check continuity between blower fan motor connector terminal
and ground.

2 (Without air conditioner) Ground Yes
1 (With air conditioner)
Does continuity exist?
MJIB0125E
YES >> GO TO 4.
NO >> GO TO 5.
