HVAC Control Components: Personalization
WARNING: This page is about a different car, the 2008 Buick LaCrosse and 2008 Buick Allure. However, it is still accessible from the selected car via links, so may be relevant.
The HVAC control module will receive information that defines the current driver of the vehicle from the driver door module (DDM) through class 2 communication. The HVAC system will memorize the following system configurations for up to three unique drivers:
- Driver set temperature
- Passenger set temperature
- Mode
- Blower motor speed (auto, speed 1, 2, 3, 4, 5, 6)
- Air conditioning (A/C) compressor request, auto ON or A/C OFF
This information shall be stored inside the HVAC control module memory. When a different driver identification button is selected the HVAC control module will recall the appropriate driver settings. When the HVAC control module is first turned on, the last stored settings for the current driver will be activated except for the rear defrost and heated seat settings.
