HVAC - '08 Impala
Here is my issue. Our Impala, when AC is on, blows cold air on the passenger side and blows hot air on the drivers side. With the key on, engine off, I can turn each side from heat to cool and can hear the blend door changing positions on both sides with no clicking. Doesn't seem to me the blend door actuator motors are the problem. What else could be going bad?
