REAR WINDOW DEFOGGERPFP:25350
Component Parts and Harness Connector LocationBIS000ZU
System DescriptionBIS000ZV
The rear window defogger is controlled by BCM and IPDM E/R.
The rear window defogger operates only for approximately 15 minutes.
Power is supplied at all times

through 20A fuse (No. 75, located in the IPDM E/R)

to rear window defogger relay terminal 3.

through 10A fuse (No. 32, located in the fuse and fusible link box)

to rear window defogger relay terminal 6.

through 50A fusible link (letter M , located in the fuse and fusible link box)

to BCM terminal 55.

through 15A fuse [No. 17, located in the fuse block (J/B)]

to BCM terminal 42.
With the ignition switch turned to ON or START position,
Power is supplied

through 10A fuse [No. 1, located in the fuse block (J/B)]

to BCM terminal 38.

through 10A fuse [No.12, located in the fuse block (J/B)]

to rear window defogger relay terminal 1.

through 10A fuse [No. 6, located in the fuse block (J/B)]

to A/C and AV switch terminal 7.
Ground is supplied

to BCM terminal 52

through grounds M71 and M72.

to A/C and AV switch terminal 13

through grounds M71 and M72.

to IPDM E/R terminals 38 and 60

through grounds E1 and E31.
When rear window defogger switch in A/C and AV switch is turned to ON,
Ground is supplied

to BCM terminal 9

through A/C and AV switch terminal 9

through A/C and AV switch terminal 13

through grounds M71 and M72.
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 unit (with out display control unit)
or display control unit (with display control unit) via DATA LINE (CAN H, CAN L).
When display unit or display control unit receives rear window defogger switch signals, indicator is displayed
on the screen.
When IPDM E/R receives rear window defogger switch signals,
Ground is supplied

to rear window defogger relay terminal 2

through IPDM E/R terminal 52

through IPDM E/R terminal 38 and 60

through grounds E1 and E31.
and then rear window defogger relay is activated.
When rear window defogger relay is turned ON,
Signals are transmitted,

through rear window defogger relay terminals 5

to rear window defogger terminal 1.
Rear window defogger terminal 2 is grounded through ground B253.
With power and ground supplied, rear window defogger filaments heat and defog the rear window.

through rear window defogger relay terminals 7

to door mirror defogger (driver side and passenger side) terminal 2.
Door mirror defogger (driver side and passenger side) terminal 3 are grounded through grounds M71 and
M72.
With power and ground supplied, door mirror defogger filaments heat and defog the mirror.
