REAR WINDOW DEFOGGER

With power and ground supplied, the rear window defogger and door mirror defogger filaments heat and defog
the rear window and door mirror.
When the system is activated, the rear window defogger indicator illuminates in the rear window defogger
switch.
Power is supplied

through rear window defogger relay terminal 3 (without door mirror defogger or side air bag) or

through rear window defogger relay terminal 5 (with door mirror defogger or side air bag)

to rear window defogger switch terminal 3 (without auto A/C) or

to A/C auto amp, terminal 23 (with auto A/C).
System Description / RHD ModelsEIS008O7
The rear window defogger system is controlled by time control unit. The rear window defogger operates only
for approximately 15 minutes.
Power is supplied at all times

through 20A fuse (No.25, located in the fuse and fusible link box) and

to rear window defogger relay terminal 3 (with side air bag) or

to rear window defogger relay terminal 5 (without side air bag).
With the ignition switch in the ON or START position, power is supplied

through 10A fuse [No.5, located in the fuse block (J/B)]

to rear window defogger relay terminal 1 and

to time control unit terminal 17.
Ground is supplied

to rear window defogger switch terminals 2 and 4 (without auto A/C) or

to A/C auto amp. Terminal 3 (with auto A/C)

through body ground M27 and M70.
When the rear window defogger switch is turned ON, ground is supplied

to time control unit terminal 35

through rear window defogger switch terminal 1 (without auto A/C) or

through A/C auto amp, terminal 22 (with auto A/C).
Terminal 27 of the time control unit then supplies ground to the rear window defogger relay terminal 2.
With power and ground supplied, the rear window defogger relay is energized.
Power is supplied

through rear window defogger terminal 3 (without side air bag) or

through rear window defogger terminal 5 (with side air bag)

to the rear window defogger.
The rear window defogger and door mirror defogger has an independent ground.
With power and ground supplied, the rear window defogger and door mirror defogger filaments heat and defog
the rear window and door mirror.
When the system is activated, the rear window defogger indicator illuminates in the rear window defogger
switch.
Power is supplied

through rear window defogger relay terminal 3 (without side air bag) or

through rear window defogger relay terminal 5 (with side air bag)

to rear window defogger switch terminal 3 (without auto A/C) or

to A/C auto amp, terminal 23 (with auto A/C).

2. Check voltage between auto amp. harness connector M52 ter-
minal 1 (BR/Y), 2 (L), 20 (L/W) and ground.
OK or NG
OK >> GO TO 2.
NG >> Check 10A fuses (Nos. 15 and 28) and 15A fuses (Nos. 19 and 24), located in the fuse block (J/
B). Refer to PG-75, "
