System Description
WARNING: This page is about a different car, the 1998 Cadillac Eldorado and 1998 Cadillac DeVille. However, it is still accessible from the selected car via links, so may be relevant.
The Electronic Climate Control (ECC) system automatically regulates and maintains selected in-vehicle temperature between 65°F (18°C) and 85°F (29°C) regardless of changes in outside air temperature. Settings of 60°F (16°C) and 90°F (32°C) provide unregulated cooling and heating, respectively. The Climate Control Panel (CCP) is the main control for selecting in-vehicle comfort levels. See Fig 1 or Fig 2 .
Main components of ECC system are A/C-Heater Programmer (ACM), Powertrain Control Module (PCM), refrigerant system, temperature sensors, and Heating, Ventilation and Air Conditioning (HVAC) module.
