Climate controls that no longer respond, or settings that do not change the airflow or temperature, can mean the module has failed. Before you swap it, look over the connectors with the engine off for corrosion, bent terminals or a loose plug, because those can also leave the controls dead. This listing is one module, and each vehicle takes one at the front.
