Why does only the heat come on the passenger side and not the driver side?

Hello, A very common issue with the Ford Edge is failure of the blend doors and blend door actuators. If you plan to repair the vehicle yourself, you will need to find which blend door actuator is not functioning to replace it, and understand the blend door could be broken inside the HVAC central housing. In many cases, the HVAC central housing behind the dashboard must be removed, so the dashboard must be removed as well.
