REMOVAL
1. Remove the front pillar garnish. Refer to EI-35, "BODY SIDE TRIM" .
2. Remove inside mirror. Refer to GW-76, "
Removal and Installation" .
3. Partially remove the headlining (front edge). Refer to EI-38, "
HEADLINING" .
4. Remove cowl top cover. Refer to EI-18, "
Removal and Installation" .
5. Apply a protective tape around the windshield glass to protect the painted surface from damage.

Remove glass using piano wire or power cutting tool and an inflatable pump bag.

If a windshield glass is to be reused, mark the body and the glass with mating marks.
WA RN ING:
When cutting the glass from the vehicle, always wear safety glasses and heavy gloves to help prevent
glass splinters from entering your eyes or cutting your hands.
CAUTION:

When a windshield glass is to be reused, do not use a cutting knife or power cutting tool.

Be careful not to scratch the glass when removing.

Do not set or stand glass on its edge. Small chips may develop into cracks.
INSTALLATION

Use a genuine NISSAN Urethane Adhesive Kit (if available) or equivalent and follow the instructions fur-
nished with it.

While the urethane adhesive is curing, open a door window. This will prevent the glass from being forced
out by passenger compartment air pressure when a door is closed.

REAR WINDOW DEFOGGERPFP:25350
Component Parts and Harness Connector LocationEIS005YM
System DescriptionEIS005YN
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 operates only for approximately 15 minutes.
Power is supplied at all times

through 15A fuses (No. 43, 46, and 47 located in the IPDM E/R)

to rear window defogger relay and heated mirror relay (located in the IPDM E/R)

through 50A fusible link (letter f , 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 switch

to rear window defogger relay (located in the IPDM E/R)

through 10A fuse (No. 59, located in the fuse and relay box)

to BCM terminal 38

through 10A fuse [No. 8, located in the fuse block (J/B)]

to front air control terminal 14.
Ground is supplied

to BCM terminal 67

to front air control terminal 1
LIIA1981E

REAR WINDOW DEFOGGER
Revision: October 20052005 QX56

through body grounds M57, M61 and M79

to IPDM E/R terminals 38 and 59

through body grounds E9, E15 and E24.
When front air control (rear window defogger switch) is turned to ON,
Ground is supplied

to BCM terminal 9

through front air control terminal 11

through front air control terminal 1

through body grounds M57, M61 and M79.
Then rear window defogger switch is illuminated.
Then BCM recognizes that rear window defogger switch is turned to ON.
Then it sends rear window defogger switch signals to IPDM E/R and display control unit via CAN communica-
tion (CAN-H, CAN-L).
When display control unit receives rear window defogger switch signals, and displays on the screen.
When IPDM E/R receives rear window defogger switch signals,
Ground is supplied

to rear window defogger relay (located in the IPDM E/R)

through IPDM E/R terminal 38

through IPDM E/R terminal 59

through body grounds E9, E15 and E24
and then rear window defogger relay is energized.
With power and ground supplied, rear window defogger filaments heat and defog the rear window.
When rear window defogger relay is turned to ON
Power is supplied

through heated mirror relay (located in the IPDM E/R)

through IPDM E/R terminal 23

to door mirror defogger (LH and RH) terminal 10.
Door mirror defogger (LH and RH) is grounded through body grounds M57, M61 and M79.
With power and ground supplied, rear window defogger filaments heat and defog the rear window and door
mirror defogger filaments heat and defog the mirror.
