11.11.3 System work principle

11.11.3.1 Work principle

Install the backdoor window defrosting switch on the instrument panel center switch assembly.
Transmit the defrosting request signal to the air conditioner control module which then receives
the input signal for the defrosting switch to control the backdoor defrosting relay to close. The
backdoor defrosting relay outputs power to the backdoor defrosting grille and left and right
rearview mirror heaters and at the same time the rear defrosting/rearview mirror heating signal
will be sent to the ECM via a dedicated line. The ECM will increase the RPM of the engine
according to needs. Rear defrosting switch is an inching button switch, and rearview mirror
heating switch is a gyration button.
