Blower Motor Circuit: Description
WARNING: This page is about a different variant/trim than selected.
The solar ventilation system and air conditioning system use the same blower motor for ventilation.
In order to be driven by each system, the blower motor switches between two different power sources using the solar ventilation relay. When the power switch is off, power from the solar ventilation system is supplied to the blower motor and when the power switch is in a mode other than off, power from the air conditioning system is supplied to the blower motor.
The blower motor controls its operation and speed using the power and signals supplied by the solar ventilation ECU when the power switch is off.
Changes its speed according to the amount of sunlight received by the moon roof glass assembly (solar panel).
