My heater won't work, or at least it won't blow hot.

We have replaced the thermostat and checked almost everything what could it possibly be so that i can have sort of a checklist of things to look over.

No hot air


Sounds like the problem lies in the thermostat, When the engine thermostat fails to close fully, the engine coolant temperature may fall. Low engine temperature causes several problems and may cause the heater to blow cool air. Make sure about that.

Why is heater not blowing hot air on 99 chevy blazer


if the fan blower is working then it must be the heater valve inline with the heater hoses. Or the selector on the dash has broken and is not connected at the back. You have tried everything else. You were correct in what you wrote above and have tried so far

My heater just stopped working, it still blows air but just not hot air, i checked the coolant and its fine, it had never over heated. so please help


check to be sure that the thermostat is closing, sounds like yours is stuck open, which happens a lot ,, if the water won't stay in the motor long enough to heat,, then you won't get any hot air coming out , follow the top radiator hose to the motor, under that housing is where you will find the thermostat , thay are pretty cheap, less than 10 bucks normally ,, I'd just replace it

Heater will not blow hot air. it blows cold air and fan blows. new thermostat and full radiator


The heater core is possibly blocked or the temperature adjuster is not working.

First check the controls to be certain that the temperature aduster is working and the flaps/doors that direct the flow of hot air are working.

If they are..........

Check heater hose temp. If one is hot and one is cold, you are not getting flow through the heater core.

Bleed it to remove an air blockage.
If that does not work, flush the system.
If that does not work, replace the heater core.

I have a 1993 Acura Ledgend. For some reason my heater does not continue to blow hot air, it does for a few minutes and then begain to blow cold air. It does this often now. It works and then it blows cold...


first check to see that you coolant level is full, check it after the engine has cooled down,so there is no pressure in the system. otherwise you possibly have a head gasket in the early stage of failure

Hi my rangerover heater is blowing out cold, everything else is working just the heater isnt...


Most likely your thermostat has failed and is stuck open. Engine coolant goes through the heater core and is used to heat the air that is blown into the cabin. If the thermostat fails, the coolant doesn't stay inside the engine long enough to absorb enough heat to make the climate control air blow hot. Change your thermostat (flush the coolant and have it replaced while you do this), and you should be back in business.

HEATER BLOWS AIR BUT NOT HOT


possibly the heater valve isn't opening allthe way,or the thermostat is stuck open not letting engine coolant get hot, check to make sure both heater hoses on firewall are hot, then if you have a small wooden mallet(not steel or metal) tap the thermostat housing and see if this dislodges thermostat from being stuck, don't hit it real hard, the housing is only aluminum

Heater and air conditioner aren't working


first check and if the thermostat is working. take it out put it in hot water. the thermostat should open up. also put a temp gauge in the hot water so you know at what temp it opens up. start there. dont forget theres more fuses under the hood for the ac unit
