Why is my heater not blowing hot Dodge Neon?

Possible Reasons for Heater Not Blowing Hot in Dodge Neon
There can be several reasons why your Dodge Neon’s heater is not blowing hot air. Here are some possible causes to consider:
1. Blend Door Issue: The blend door in the heater box may be binding up, preventing hot air from being diverted through the heating ducts. The blend door is cable actuated and is built into the heater box, which requires removing the dashboard to access it.
2. Water Pump Problem: If your temperature gauge shows that the engine is running hotter than normal but there is no heat coming from the heater, it could indicate issues with the water pump. You can try taking the vehicle out of gear and revving the engine a little to see if it helps.
3. Heater Core Blockage: A blockage in the heater core can restrict the flow of hot coolant, resulting in lukewarm air blowing from the heater. This can be caused by a buildup of debris or sediment in the heater core. Flushing the heater core may help resolve this issue.
4. Faulty Blower Motor: If the blower motor is not functioning properly, it may not blow enough air across the heater core to generate hot air. Checking the blower motor and the associated wiring for any issues is recommended.
5. Other Potential Causes: Other potential causes for the heater not blowing hot air in a Dodge Neon include a faulty thermostat, a defective blend door actuator, a dirty cabin air filter, or a problem with the heating system’s controls.
It’s important to note that diagnosing and fixing the issue may require professional expertise. If you are unable to resolve the problem on your own, it is recommended to consult a qualified mechanic for further assistance.

You may want to check for leaks as well if you just recently refilled your coolant.
