Imagine it’s a hot summer day and you’re looking forward to a refreshing drive. But instead of cool air, you’re greeted by stifling heat. The culprit? Potentially the climate control unit, often referred to as the “brain” of the air conditioning system.
What is a Climate Control Unit?
The climate control unit is a complex electronic module responsible for controlling and regulating the car’s air conditioning system. It receives signals from various sensors that measure interior and exterior temperature, solar radiation, and other parameters. Based on this information, the control unit regulates the AC’s functions, such as fan speed, temperature control, and air distribution.
