Problem overview

Some Dodge Avenger owners report experiencing an issue where the driver side blows hot air while the passenger side vents only emit cold air, which may indicate a manufacturer defect. This problem is often linked to malfunctions in the blend door actuator, which controls the mix of hot and cold air, leading to uneven temperature distribution in the vehicle. Additionally, a faulty heater core can also cause inconsistent heating, resulting in one side blowing hot air while the other remains cold. To address this issue, some owners find it necessary to check the blend door actuator for proper functionality, as replacing a faulty actuator may resolve the temperature disparity. Others may need to have the heater core evaluated by a professional, as a defective heater core could require repair or replacement. It is advisable for owners to consult a qualified mechanic for an accurate diagnosis and appropriate solutions, as well as to perform regular maintenance on the HVAC system to prevent such issues in the future.
