Air Delivery System
WARNING: This page is about a different car, the 1995 Cadillac Seville, 1995 Cadillac Eldorado, and 1995 Cadillac DeVille. However, it is still accessible from the selected car via links, so may be relevant.
The HVAC assembly incorporates most of the air conditioning components into one assembly. The function of the air delivery system is to distribute airflow throughout the vehicle. Major components of the HVAC module include air inlet valve, blower motor, evaporator core, air-mix valve, heater core, up-down valve, and A/C-defogger valve. See Fig 1. Some models have an auxiliary blower in the console to direct air to rear seat occupants.
