POWER MIRROR DEFOGGERS
Circuit Operation
Voltage is applied at all times through the EB-19 IGN.
B2 fuse, to the rear window defogger relay coil. With the
starter switch in ON, voltage is applied through the
C-16 (RR WIPER) fuse to the rear window defogger
relay contacts.
When the rear window defogger switch is depressed,
the PCM receives a ground input from the switch and, in
turn, the PCM provides ground to the coils of the rear
window defogger relay. The contacts close, applying
ignition voltage to the rear window defogger, rear
window defogger indicator lamp (through the C-9 &
C-10 (REAR DEFOG.) fuses), and the left and right
power mirror defoggers (through the C-8 (MIRROR
DEFOG.) fuse). The PCM acts as the timer for the rear
window defogger relay and keeps the contacts closed,
maintaining the operation of the rear window defogger,
left and right mirror defoggers and indicator lamp for 10
minutes or until the ignition is turned to “ACC” or “OFF”,
or the rear window defogger switch is depressed again.
The rear window and mirrors heat to remove any fog
from the glass and the indicator stays on to remind the
driver that it is in use.
