Have a 2012 Impala that is blowing cold air on the driver and warm air on the passenger side do they have dual heater cores or what might be the problem

It could be a faulty temperature control actuator on the driver side or a broken blend door. I’m not sure if your car has several temperature sensors, if it has – it could be a faulty temp sensor. However, the easiest way is to read the trouble codes and try to see if the actuators are moving when selecting temperature.
