Why is my Dodge Durango heater not getting hot?

Possible Causes for Dodge Durango Heater Not Getting Hot
Based on the search results, there are several possible causes for a Dodge Durango heater not getting hot:
1. Heater Blower Motor: The heater blower motor may be malfunctioning, preventing the hot air from being blown into the cabin.
2. Low Coolant Level: Insufficient coolant in the system can cause the heater core to not receive enough hot coolant, resulting in a lack of heat. Checking the coolant level in the overflow reservoir can help determine if this is the issue.
3. Clogged Heater Core: A clogged heater core can block the flow of hot coolant, leading to a lack of heat. Flushing the heater core can help remove any rust or mineral deposits that may be causing the blockage.
4. Thermostat Issues: A faulty thermostat can prevent the engine from reaching its optimal operating temperature, which can affect the heat output. Checking the temperature of the water pump housing can help determine if the thermostat is functioning properly.
5. Blend Door or Control Issues: Problems with the blend door or control for the water flow through the heater core can also result in a lack of heat. Checking the temperature control and the control valve for the heater core can help diagnose these issues.
It is important to note that these are just possible causes and further diagnosis may be required to pinpoint the exact issue with the Dodge Durango’s heater.
Conclusion
If your Dodge Durango’s heater is not getting hot, it could be due to various reasons such as a malfunctioning heater blower motor, low coolant level, a clogged heater core, thermostat issues, or blend door/control problems.
