I have 04 Impala and on the driver side blows cold air and on the passenger side it blows hot. I replaced the thermostat beacuse temperature was running cold. Now the temperature is ok but still blows cold air on one side and hot on another.

The heat in that vehicle is controlled by a blend door that regulates heated air flow. It is operated by an electric motor/actuator. The problem can be that the actuator is stripped or inoperative or the door itself could be damaged. This is what needs to be determined by examining the actuator and see if it is responding to heat change commands or not.

I don't know what your abilities are. I know you have to be rubber man to get up under that dash.
