The Chevrolet Blazer A/C Switch puts cabin temperature under the driver's instant control by signaling the climate control brain to begin the cooling or heating process. Inside the dash, the climate control module translates the A/C Switch command to the relays, power modules, and blower motor to provide the selected airflow. Early Chevrolet Blazer models had a simple A/C Switch that opened or closed the circuit so that the compressor and fan were either on or off. Newer Chevrolet Blazer models incorporate the A/C Switch into an automatic temperature control, in which the same button or dial works in tandem with a power module that can vary blower speed in countless steps, conserving fuel by preventing constant full blast operation. In both designs, a healthy switch prevents the system from running nonstop, stopping wasteful parasitic drag and keeping winter heat or summer chill exactly when it is wanted. If the A/C Switch or its relay sticks, even the greatly smart Chevrolet climate module cannot halt unwanted airflow, so every ride in the Blazer is dependent on a responsive switch.
