assembly from the door panel.
Installation
Installation is in the reverse order of removal.
Inspection after Removal
Check the regulator assembly for the following. [If a problem is
detected, grease or replace it as shown].
Gear wear
Regulator deformation
Grease condition for each sliding part

POWER WINDOW REGULATOR ASSEMBLY
Disassembly
Remove the power window motor from the regulator assembly.
Assembly
Assembly is in the reverse order of disassembly.
Inspection after InstallationEIS00954
FITTING INSPECTION
Make sure the glass is securely fit into the glass run groove.
Lower the glass slightly [approx. 10 to 20 mm (0.39 to 0.79 in)], and make sure the clearance to the sash
is parallel. If the clearance between the glass and sash is not parallel, loosen the regulator bolts, guide rail
bolts, and glass and carrier plate bolts to correct the glass position.

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
to BCM terminal 67 and
1. BCM M18, M20 (view with glove box
removed)2. Front air control M33 3. A. Rear window defogger ground
connector D413
B. Rear window defogger connector
D412
C. Condenser D409, D411
4. IPDM E/R E46, E48 5. Door mirror LH D4, RH D107 (with
heated mirrors)6. Heated mirror relay M48 (with
heated mirrors)

to front air control terminal 8
through body grounds M57 and M61
to IPDM E/R terminals 39 and 59
through body grounds 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 3
through front air control terminal 8
through body grounds M57 and M61.
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 via CAN communication (CAN-H, CAN-L).
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 terminals 39 and 59
through body grounds E15 and E24
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 (with heated mirrors), power is supplied
through heated mirror relay terminal 5
to door mirror (LH and RH) terminal 1.
Door mirror (LH and RH) is grounded through body grounds M57 and M61.
With power and ground supplied, rear window defogger filaments heat and defog the rear window and door
mirror filaments heat and defog the mirrors.
