    Same exact problem... I replaced coolant and thermostat with a new 195 degree unit. No help. Could the heater core be gunked up?

Your coolant may be bad and is not holding heat. you can have it tested at a local repair shop. if its bad have the cooling system flushed. or your thermostat may be opening too soon not allowing the coolant to heat up enough and need replaced

I only get like warm air on floor but no heat anywhere else. 2001 ford f150


Either your heater blend door is failing, your core is plugged, or you have poor coolant circulation. checking the temp of both heater hoses will rule out the core usually. (Warm engine, heater ON, both hoses should be HOT and near same temperature). If 1 hose is hot and the other cold, your core may be plugged. If both hoses are HOT, and still no heat inside, your heater box is likely not directing the warm air properly on the interior. If neither hose is hot or warm, and heater is ON, your heater control valve should be checked to make sure it is flowing coolant to the heater.

If all THAT seems to pass (heater valve definitely open) an d still low or not heat inside and both hoses the same, your water pump may not be making enough flow to feed the engine and the heater. Typically if this is the problem, holding the engineat high rev (3000+) for 5-10 minutes will cause the heater to warm up mostly, and then dropping the RPM to 1000 or 1500 you will feel it cool off rapidly. If that is the case, you will need cooling system repairs.

Long time before heater blows warm air


That seems pretty normal, the heater works by blowing excess heat from the engine coolant. So the coolant has to be warmed completely for the heat to work, you can get a heater that plugs into your cigarette lighter that will heat the vehicle instantly.

I have no heat in my 2002 Dodge Stratus. I have changed the thermostat and flushed the heater core? What else could this be?


See if your library has a Stratus shop manual and check the heating system chapter. You didn't say if the engine was reaching operating temperature or not. If the engine is warm but you are not, I would say the problem is in the heat exchanger somewhere. If your engine is cold, you can't really expect the heater to get warm, now can you. Then you have a different problem to chase.

Lack of water on your floor means your heater core is not leaking. It could still be plugged somewhere. The fact that you get some heat initially, but it turns cold when you turn the fan on, sounds like a lack of adequate warm water to the heater core to me. If the engine is warm, it could be a circulation problem of some sort.

The heater in my 1991 wrangler doesnt give out warm air. No real heat

No heat in car..thermostat new,flushed system,flushed heater core..still no heat


Feel the heater hoses under the hood when the vehicle is warmed up. They should both be warm.
You may also have a valve that shuts off the coolant flow on the heater hoses. The valve may be faulty.
If both heater hoses are warm up near the firewall where they enter the vehicle then you might have a bad solenoid or switch that is not operating the blend air door that moves between the A/C evaporator and heater core.

No heat,replaced heater coil but no heat when switch on to the heat,fan comes on but no heat


No heat = no motion. If there is no heat in your car there is no molecular motion (no molecular bond) and the world as you know it will literally fall apart. Won't even be elements left, just random neutrons being pounded by protons and electrons colliding at an alarming rate.
Assuming you mean that your A/C works fine and the only problem is the air being blown out is not warm as it should be on heat, could be a couple of things.
Valve not sending coolant to heater core. To check this just warm the car up, turn on the heater, and pop the hood. Find where the heater core hoses connect at the firewall. Feel each side (in and out), they should both be very warm. If not very warm, your heater core is not getting any heated water to share with you in the cabin. Follow the hoses from the firewall to wherever they go. If there is a device connected inline, feel both sides of it. If the 'other' side is hot, the valve isn't turning on. This is what you hope the problem is, cheap and easy.
Blend door not operating properly. This is the flapper door within your heater/AC box that puts air through the heater core or the AC core. Checking or fixing it means removing the dash, which isn't any fun. Hope it's the valve above.


good luck

First thing in the (cold) mornings heater wont work. water gauge flux's up and down weird . then about 20 mins into driving its warms up


Your engine coolant is what your heater gets the heat from. You need to start your car and let it warm up for awhile before any heat will come. This is how most cars heaters work. Yours sounds like it is working fine; most cars take a little while to warm up.

Hope this helps!
