2004 Cadillac CTS - Climate Control Module

What Does the Climate Control Module Do?

The climate control module, also known as an A/C or heater control module, is a computer used to adjust your vehicles heating and air conditioning in your vehicles cabin. The climate control module controls the vehicle's heating and cooling functions electronically. Depending on the vehicle, climate control modules collect data from inside and outside of the car to maintain the correct temperature in the vehicle's cabin, depending on external and internal temperature readings. Because the climate control module regulates the entire electronic and mechanical portion of your vehicle A/C and heating systems, including fan speed and temperature, problems with the module can greatly effect the entire system. Over time and use, the climate control module can break down. When a climate control module begins to fail, you may notice signs of inconsistent cooling or uneven air distribution, or you may have out of date software.
