If your 2013 Dodge Durango's heater isn't working, the likely culprit could be the blend door actuator. This small electric motor is connected to sensors in your car's climate control system, allowing you to adjust the temperature and air flow. The actuator controls an air control door pivot using a plastic gear set driven by the motor. If the plastic gears become weak and break, the actuator may malfunction.
If the heater in a 2013 Dodge Durango is not working, the problem is probably with the blend door actuator. It could also be a problem with the motor or blower system.
