"FUSE AND FUSIBLE LINK BOX".
OK or NG
OK >> GO TO 2.
NG >> GO TO 10.
2.CHECK BLOWER MOTOR POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect blower motor connector.
3. Turn ignition switch ON.
4. Turn the blower control dial to select any mode except off.
5. Check voltage between blower motor harness connector M94
terminal 2 and ground.
OK or NG
OK >> GO TO 12.
NG >> GO TO 3.
3.CHECK BLOWER MOTOR RELAY (SWITCH SIDE) POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect blower motor relay.
3. Check voltage between blower motor relay harness connector
E28 terminals 3 and 6 and ground.
OK or NG
OK >> GO TO 4.
NG >> Repair harness or connector.
4.CHECK BLOWER MOTOR RELAY
Refer toAT C - 8 6 , "
Blower Motor Relay".
OK or NG
OK >> GO TO 5.
NG >> Replace blower motor relay.
5.CHECK BLOWER MOTOR RELAY (SWITCH SIDE) CIRCUIT FOR OPEN
1. Turn ignition switch OFF.
2. Disconnect blower motor relay connector and blower motor con-
nector.
3. Check continuity between blower motor relay harness connector
E28 terminals 5 and 7 and blower motor harness connector M94
terminal 2.
OK or NG
OK >> GO TO 6.
NG >> Repair harness or connector.Fuses are good.
