REAR WINDOW DEFOGGER
Revision: June 20062007 Versa
REAR WINDOW DEFOGGERPFP:25350
Component Parts and Harness Connector LocationEIS009CK
System DescriptionEIS0 09 CL
The rear window defogger system is controlled by BCM (body control module) and IPDM E/R (intelligent
power distribution module engine room).
The rear window defogger only operates for approximately 15 minutes.
Power is supplied at all times
through 15A fuses (No. 46 and 47, located in the IPDM E/R)
to rear window defogger relay
through 10A fuse [No. 5 (with heated mirrors), located in the fuse block (J/B)]
to heated mirror relay terminal 3
through 40A fusible link (letter g , located in the fuse and fusible link box)
to BCM terminal 70.
With the ignition switch turned to ON or START position, power is supplied
through ignition relay
to rear window defogger relay (located in the IPDM E/R)
through 10A fuse [No. 6, located in the fuse block (J/B)]
to BCM terminal 38.
Ground is supplied

Revision: June 20062007 Versa
DIAGNOSTIC PROCEDURE FOR BLOWER MOTOR
SYMPTOM: Blower motor operation is malfunctioning.
1. CHECK BLOWER MOTOR OPERATION
1. Turn ignition switch ON.
2. Check blower motor operation at each fan speed.
OK or NG
OK >> Inspection End.
NG >>
Blower motor does not operate at any speed, GO TO 2
Blower motor does not operate at one or more of the four speeds, GO TO 8.
2. CHECK POWER SUPPLY FOR BLOWER MOTOR
1. Turn ignition switch OFF.
2. Disconnect front blower motor connector.
3. Turn ignition switch ON.
4. Check voltage between front blower motor harness connector
M62 terminal 1 and ground.
OK or NG
OK >> GO TO 3.
NG >> Check power supply circuit and 15A fuses [Nos. 15 and 17, located in the fuse block (J/B)]. Refer
to PG-76, "
FUSE BLOCK-JUNCTION BOX (J/B)" .
If fuses are OK, check harness for open circuit. Repair or replace if necessary.
If fuses are NG, replace fuse and check harness for short circuit. Repair or replace if necessary.
3. CHECK FRONT BLOWER MOTOR
Check continuity between front blower motor terminals 1 and 2.
NOTE:
Ensure that there are no foreign particles inside the A/C unit assem-
bly for a smooth rotation of the blower motor.
OK or NG
OK >> GO TO 4.
NG >> Replace front blower motor. Refer to MTC-68,
