Climate controls that no longer respond, or settings that will not change, can mean the module has failed. A blown fuse, a failed blower motor resistor or a worn blend door actuator can also leave the controls dead or the airflow off, so find the cause before you buy a module. One module goes in each vehicle, and this listing is a single unit.
