Why is my heater not blowing hot air Dodge Ram 1500?

Possible Causes for Heater Not Blowing Hot Air in Dodge Ram 1500
There can be several reasons why your Dodge Ram 1500 heater is not blowing hot air. Here are some possible causes based on the search results:
1. Blend Door Issue: One possible cause is a problem with the temperature blend door inside the dash. If the inlet and outlet hoses to the heater core are both hot, but the air coming out is not as hot, it could indicate a problem with the blend door.
2. Heater Core Problem: If the inlet and outlet hoses to the heater core are both hot, but the air coming out is cooler, it could indicate a problem with the heater core. Flushing the heater core might help in some cases.
3. Thermostat Issue: A faulty thermostat can also cause the heater to blow cold air. If the thermostat is not opening properly, it can prevent hot coolant from flowing through the heater core.
4. Coolant Level: Low coolant level can result in the heater blowing cold air. Make sure to check the coolant level and top it up if necessary.
5. Air Pocket: Another possible cause is an air pocket trapped in the cooling system. This can prevent hot coolant from reaching the heater core. “Burping” the system by removing air pockets might help resolve the issue.
It’s important to note that these are just possible causes based on the search results. To accurately diagnose and fix the issue, it is recommended to consult a qualified mechanic or contact your local Dodge dealership for assistance.

A common cause is a low coolant level, which can happen from a leak or not having enough coolant put in. The coolant carries heat from the engine to the heater core, warming the air before it’s blown into the cabin. The air won’t get warm if there’s not enough coolant or it can’t flow well.
