Component Parts and Harness Connector LocationEIS001PH
System descriptionEIS001PI
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
lto rear window defogger relay terminal 3 or 5 (3:with door mirror defogger, 5:without door mirror defogger)
lthrough 20A fuse (No.25, located in the fuse and fusible link box) and
lto rear window defogger relay terminal 6 (with door mirror defogger)
lthrough 10A fuse (No.27, located in the fuse and fusible link box).
lto time control unit terminal 1
lthrough 10A fuse (No.28, located in the fuse and fusible link box).
With the ignition switch in the ON or START position, power is supplied
lthrough 10A fuse [No.5, located in the fuse block (J/B)]
lto rear defogger relay terminal 1 and
lto time control unit terminal 17.
Ground is supplied to terminal 2 of rear window defogger switch through body ground M70.
When the rear window defogger switch is turned ON, ground is supplied
lthrough terminal 1 of the rear window defogger switch
lto time control unit terminal 35.
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
lthrough terminals 5 and 7 of the rear window defogger relay
lto the rear window defogger and door mirror defogger.
The rear window defogger has an independent ground.
With power and ground supplied, the rear window defogger filaments heat and defog the rear window.
When the system is activated, the rear window defogger indicator illuminates in the rear window defogger
switch.
Power is supplied
lto terminal 3 of the rear window defogger switch
lfrom terminal 3 or 5 of rear window defogger relay. (3:witout door mirror defogger, 5:with door mirror
defogger)
