Check the density of the coolant. Might not have enough pure antifreeze in it. If you recently changed antifreeze, you should have replace with one gallon pure 100% antifreeze and filled remainder with 50/50 mixture. Did you burp the system after you changed all that stuff. Air in line will cause a vapor locj and will not heat well. !00% antifreeze is bad for your system. Last, you may have headgasket problems.

SOURCE: 99 jeep cherokee problem w/ heat

It could be a flap but more likely you have a air trapped in the heater core or the hoses connecting the heater core when refilled the system after your repair.
Loosen the supply hose that go to the heater core at the highest point and run engine until coolant comes out.

It is your heater core, there is nothing else left.

The heater housing is usually under the dash, and it must be removed to gain access to the heater core.Procedures for removing a dash, and heater core vary. But for the core:
The heater housing must be removed, and then you
"remove the panels" or "split the case"1c3d50c.gif (Usually screwed together.)
Remove the coolant hoses, the cable and vacuum control line.
Remove the heater core bracket and clamps.
To install the new heater core, reverse the removal steps.
Core leaks **** because of the core's location deep within the firewall/ dashboard of the car.
So remember to liquid test your new one before you put it back in, or you could be sorry.

SOURCE: 1996 jeep grand cherokee blower works but no heat

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.

SOURCE: Have no heat. Have replaced heater core,

I don't know your vehicle, but does it have a blower door tucked in where the heater core is? If it DOES and that's broken then it could be the whole problem. It would mean it isn't switching from the A/C side of things to the heat side of them. Hope this helps, good luck! Also, just looked up the proper name for what I'm talking about, it's called a "blend door" and I think your car has one. It's what I would check, again, good luck!

Drained radiator added prestone Radiator flush refilled and started overheating, drained radiator replaced thermostat and now I get no heat from heater,Radiator water is hot


disconnect the heat hoses going into fire wall , put hose into one with pressure and flush as it sounds like it could be bloked in the heater core,the other thing that could be the problem be the hot ,cold switch as it restricts the flow to makes the heater hoter or colder , it might need tlc or replacing as it is manaul not elec

No heat , replaced radiator , water pump, rad. cap , hoses and flushed system twice.blows cool air.whats left?


Thermostat.? if you haven't? Do it first then try it. While the car is running for a while touch the heater hoses that lead to the firewall. if one is cold and one is hot? You have a blocked Heater core. Follow the hoses back to the engine. Unconnect them both. By using a garden hose flush out the heater core do one side and then reverse by doing the other hose Lots of junk will come out so be care ful. Mistake people make is "Flushing the system" That doesn't mean your flushing the heater core.
Seeing that you have done everything else it could be the thermostat which you didn't list or the heater core being clogged. When you finished installing the thermostat and flushing the heater core out. Replenish the coolant system . If you have a bleeder on the thermostat housing? use it . loosen it and top off the fluid until you see fluid comeout of the bleeder. The system being air bound would cause no heat..

83 ford ranger no heat ,new heater core,thermostat,blower motor,runs at normal temps,noticed one heater hose very hot yet the other one which is ran into a metal line going to the engine or ekg valve is...


it sounds like you have a air blockage, or the cooling system needs flushed. to flush system go to ( autorepair.about.com/od/regularmaintenance/ss/coolant_f...) click on 3rd one down. remember to bleed air out of system, this works the best. turn heater and blower on high, start adding coolant. start car let it idle till radiator thermostat opens. when top radiator hose gets hot you should have heat. some vehicles have a bleeder to let air from system. when filling putting coolant in system. if it does, then open bleeder while engine running and putting in coolant untill there are no air bubbles coming out. have a good day !! when doing flush if need be. you can go to any auto parts store and buy radiator flush. follow directions on the back ( prestone is best )

No heat and fan only works on high


The fan only working on high is due to a defective blower motor resistor pack which must be replaced. No heat can be a clogged heater core, defective heater control valve, or thermostat stuck open. On a 8 year old car it is time for a full cooling system service. Drain, flush, replace the thermostat, and refill with a 50/50 mix of antifreeze and distilled water.

My heater is not working in my 2001 honda civic. Is it my thermostat?


Does the heater blow cold air from the vents or do you mean the there is no airflow from the vents? cold air from the dash vents when the heater control valve is set fully hot could be an air pocket in the cooling system. The radiator sits slightly lower than the engine causing air pockets to get trapped in the engine when you replace the coolant. you'll have to purge the cooling system to restore flow to the heater core. No airflow (blower motor inop) this could be a bad blower motor transistor. pin test the blower motor circuit.

Heating / Cooling System Malfunction


all mazda 929 have this problem when the coolant level is dropped
the heater core has no fluid in it since it ts off of the engine block . hence it cannot recive any coolant to heat the car. the best way to fix this is bleed the system of air . when filling coolant squezze the return hose with the cap on the rad it will force fluid bact to the core and push the air out
once you do this a few times you will see the rad fluid droped fill it up and run the car . this should solve this problem
