Ford Edge heating issue with only passenger side vents working due to valve malfunction on Ford Edge

Some Ford Edge owners report experiencing heating issues where only the passenger side vents are working while the driver's side vents are not. These problems may stem from a malfunctioning blend door actuator, which can prevent proper temperature regulation. Additionally, some owners find that a lack of airflow from the dashboard vents indicates potential issues with the fan or blower motor, possibly due to a blown fuse, bad relay, or a faulty blower motor. In cases where the AC blows hot air on the driver's side and cold air on the passenger side, checking the actuator wiring connectors has been suggested as a solution. Some users have resolved similar issues by adding refrigerant, such as a can of 134a (AC Pro). It is recommended that owners check these components to effectively diagnose and address the heating problem.
