Dodge Nitro no heat issue despite thermostat replacement and radiator flush on Dodge Nitro

Some Dodge Nitro owners report experiencing a no heat issue even after replacing the thermostat and flushing the radiator. These owners have identified several potential causes, including a clogged heater core that prevents proper heat circulation, a faulty blend door actuator that fails to direct hot air to the vents, and a malfunctioning water pump that results in inadequate coolant circulation. Additionally, some have noted that a dirty cabin air filter can restrict airflow, negatively impacting the heating system's performance. Furthermore, issues with the HVAC control unit may also hinder the heating functionality. In such situations, it is advisable to inspect these components further and consult with a professional mechanic or dealership service center for effective diagnosis and resolution.
