WINDOW / GLASS  WINDOW DEFOGGER SYSTEM  Rear Window Defogger System does not Operate  


DESCRIPTION

When the window defogger switch on the center cluster module control assembly (window defogger switch) is pressed, the operation signal is transmitted to the air conditioning amplifier assembly via LIN communication. When the air conditioning amplifier assembly receives the signal, it turns on the defogger relay (DEF) to operate the window defogger system.
