DESCRIPTION
When the rear window defogger switch on the air conditioning control assembly is pressed, the operation signal is transmitted to the air conditioning amplifier assembly through the LIN communication line. When the air conditioning amplifier assembly receives the signal, it turns on the RR DEF relay to operate the rear window defogger.
