When the car is in park you get heat on the passenger side of the car but only cool on the Driver side. When moving the driver side get cooler and the passenger side is only warm. I've heard that it could be the Blend Door Actuator but I haven't been able to find anything about the part for this particular car. Could it be something else or is it something along those lines?
