If your heat is blowing out cold air and the antifreeze level is low, it could indicate a coolant leak or an issue with the heating system. Low antifreeze can lead to inadequate heating because the engine may not be able to produce enough heat to warm the cabin. Additionally, low coolant levels can cause air to enter the heating system, disrupting proper heat circulation. It's important to check for leaks and refill the coolant to ensure proper heating functionality.

it could be thermostat stuck open ,low antifreeze, also could be ambiance temperature sensor,or the actual temperature controls on your heat and cool panel in the car.I have also seen a cadi that the heater core would clog up from deposits and would not heat but it did not bother the cars cooling as far as radiator,just would blow cold air .also check all your fuses.
When the heat is on why would the back vents of a 2004 dodge durango blow cold air and the front blow hot?
The control for the heat on the dash has a control for the back seat and also has a setting that says something like "Rear Control". This allows the passengers in the back seat to control their heat independently via a temperature control in the back seat (on the back of the center console). So you could have the heat on in the front and the rear on "rear control" and if the passenger in the back has set their control to cold, it wold blow cold air in the back even though you have the heat on in the front.
