Rear Window Defogger System does not Operate: Description

When the rear window defogger switch is turned on, a rear window defogger activation request signal is sent via the CAN communication line to the air conditioning amplifier. Then the air conditioning amplifier operates the rear window defogger. When the on signal from the switch is received, the defogger relay (DEFOG) is operated for 15 minutes. Also, if the off signal from the switch is received within 15 minutes, the defogger relay (DEFOG) operation is stopped.
