7. Remove the regulator bolts, and then remove the regulator
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

Assembly is in the reverse order of disassembly.
Inspection after InstallationINFOID:0000000001704165
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
Component Parts and Harness Connector LocationINFOID:0000000001704166
System DescriptionINFOID:0000000001704167
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.

REAR WINDOW DEFOGGER
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
• 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.
