If one side of your 2003 Impala's AC blows heat while the other side blows cold air, it could be due to a malfunctioning blend door actuator, which controls the flow of air between the heater core and the AC evaporator. Another possibility is a blocked or leaking duct that affects airflow distribution. Additionally, low refrigerant levels or a problem with the AC system could also cause uneven cooling. It's best to have the system inspected by a professional to determine the exact cause.
