Is the engine getting up to normal temp? ck if the heater valve is operational. if the engine is getting hot, and the valve is working, what is the condition of the coolasnt? should be green. If its brown/rusty,the heater core could be plugged. you can flush the core using a water hose.

I only have luke warm air coming out my ford expedition (2002) does NOT overheat ! i had it flushed out and new anti freeze put in . still kuke warm air


When you said you had it flushed out, were you talking about the radiator or the heater core. The heater core is a miniature radiator. It can get gummed up just like the big one. You will probably have to remove the heater core and have it rodded out by a radiator shop. If you have done that already then there is a problem with the regulator for the heater. Usually it is a simple valve type open and close system to allow more or less hot water into the heater core.

Heater not working, heater core is getting hot, but vehicle is not getting warm inside


If the heater core is getting hot, you could have a problem with a blend door under the dash or the HVAC controller which opens and closes the doors.

Why heater only warm


Either your thermostat is broken and jammed open (this means the water in the heater matrix will take forever to get hot) or you have an air-lock in the heater matrix. To check the thermostat, the engine should get too hot to touch before the radiator gets even warm. If they all get warm together, your thermostat is faulty. To bleed the heater matrix, uncouple the higher of the two hoses from the bulkhead an top up the water resevoir until you get flow from the loosened heater hose.

The heat dose not seem to be getting as warm as it use to


First of all see if temp gauge (after warming up) is getting up to normal temp ,were you have normally seen it, if not I would replace the thermostat next check the heater hoses. are kinda a bear cat to get to but you need to check to see if they are both getting hot and about equal temp one to the other,if the hoses are both getting hot and the temp is getting up to the normal mark,then it is very probably that you have a blend door or blend door motor problem, which are very extremely involved and if you are not a highly skilled tech I would not recommend it . It requires pulling the complete dash out of the vehicle to remove the heater box from under the dash, this is very common problem with this year ford expedition, sorry I don't have better news ,but hopefully your lucky and its only a thermostat problem

Heater blowing slightly warm air, but certainly not hot enough for pa winters. what should i try to fix first?


You may have to replace your heater core . Heater cores are kinda like you outside ac unit and if you stand by it you can feel all the hotter air blowing from it to the cooler atomosphere!!!! So basicly your heater core are alumminum fins that your blower pushes recycled heated motor air through', and into the cab . Maybe the blower is weak . Check your fuses and hoses!!!!

94 dodge intrepid blows kinda warm but not very warm what do I do? We changed the thermostat


Since your blower is working and it is a heat issue,thats where we'll start,First thing is have you checked the coolant level in the radiator when engine is cold,make sure it is filled to top,next verify you have coolant in reserve ,Start your van and get it up to normal operation temperature,If your heat gauge on the dash works correctly it should be 190 degrees,Now lift the hood and locate the two heater hoses going into the heater assembly at the fire wall,Both hoses should be hot to hold on to,if both are hot and no heat inside your problem will be the blend air door in heater assembly.
if neither hose is that hot you need to replace the thermostat in the engine to get it up to 195 degrees.
if one hose is hot and one is luke warm then the heater core is blocked and to blame. hope this helps you.

1996 Dodge Dakota heater doesn't get very hot only gets warm


it could be the heater controls itself i had a 95 ford f150 that did the same thing i replaced everything i could as i live in upstate ny and in the winter it gets pretty cold so replaced all i could ,heater coil,radiator,thermostat,coolant and nothing a local mechanic told me to check the control in the dash to see if it was going all the way to the hot position. i took the dash apart to get to it and checked it and the cable that mmoves the valve on the heater coil was stretched so it wasnt going all the way to hot. not that its the same thing but its a place to start
