2014 ford Taurus ac works on driver side but heating on passenger side
2014 ford Taurus with dual control. Ac works on
driver side but can't on passenger side blowing hot
Without knowing what options this car has, it could be a dual-zone system that's set to operate this way; you can adjust the temperature causing heat in one quadrant, and cold in another. This also could be defects in the actuators for the doors that direct air to different locations in the car or the one that throttles between hot/cold. The actuators are small boxes mounted on the ductwork and they sometimes break. If this is the problem, just replace the actuators.
