no heat from heater?

You have a large air pocket in the cooling system. Refill with coolant.

This guide will help us fix the problem

Please run down this guide and report back.

i have tried to get the air out it is supposed to vent itself through the the cap right? I have also tried the bleeder screw but no luck so I flashed out the heater core like the guide suggested and BAM all fixed!

Glad you could get it fixed, that kind of problem can be tough. Please use 2CarPros anytime we are here to help.

my air conditioning blows cold, but my heat will not come on. last yr i had this problem in reverse but, once i got it to blow cold i did not try to turn the heat back until now, and it just blows cold. any advice i will appreciate. thank you

The heat in that vehicle is controlled by a blend door that regulates heated air flow. it is operated by an electric motor/actuator. The problem can be that the actuator is stripped or inoperative or the door itself could be damaged. This is what needs to be determined by examining the actuator and see if it is responding to heat change commands or not.

My heat blows out cold until the car reaches 240 degrees. Then it goes down to 200 and the heat works. This morning it went up to 260degrees and my car woouldn't go over 40 miles an hour. Finally it went back down to 200 degrees the heat went on and I was fine. Do you know what the problem is?

Change the thermostat, sounds like it is sticking. Now is also a good time to flush and refil the cooling system.

The car wont make any heat in the heater even when the motor is hot.What could be the trouble?I change the thermostaat and its full of antifreeze.Thanks in advance for any help.

im having this prblem but i changed my hoses then i was bleeding it out and it still wont blow hot air

No heat
Check heater hoses if both hot
If not air in system
Elevate front of car and check coolant and add if needed
Check lower intake manifold gasket for leak
And if loosing coolant check head gasket
If heater hoses hot and no heat check and suspect blend door and or actuator
if one hot and one not flush heater hose

I recently had intake manifold gaskets and thermostat replaced. Now the temperature gauge reads below normal when driving and blows cold air, but if I leave it idling it gets to normal and will blow somewhat warm air. Please help, pulling my hair out and freezing to death.

first check the coolant then check thermostat. if hoses going into heater are hot then it may be a blend door in heater which you should pull the HVAC fuse inside car with key on for sixty seconds may let actuator reset then reinstall it.

my pontiac grand am 2003 heater does not work properly, some day I have full heat, the next I have half heat and another day no heat.... please help me

What is your normal engine operating temp in degrees F? Does the engine reach normal temp? Are the heater hoses hot when problem occurs? Another possibility might be the temp door, under the dash. You would need to visibly/physically check door when problem is ongoing.

my temperature is 194 F most of the time, it reach 215 F sometimes but it rare. the heat continue to be alternative whatever the temps of my engine. I try to change the heater mode setting and the heat level setting too but nothing work... I have not checked the heater hoses, I just dont know where beginning to check

That operating temp is too low. Do you live in an extremely cold area? Your low speed cooling fan won't even turn on till about 223 degrees. Maybe an issue with thermostat stuck open?

I'm living in Quebec, in Canada, its extremly cold in the winter, I will check the thermostat position and the heater hoses and if dont have positive results, I will tell you, thank you very much

No problem.

Grand am Gt, Sometimes blows hot air, then will switch down to cool by itself, always blows COLD air when at an idle or stop. Thermometer problem??? Getting cold here in Mi, If I turn on heater first it takes forever to get hot air, then sometimes it will start blowing cooler air on its own. Also whenever I idle or come to a stop it always blows out cold air? Coolant level is good. Is not overheating by temp guage

Three things to check. First, make sure the engine is operating at a normal operating temp. Next, when it gets cold, feel both heater core hoses with the engine running and the heater on. Both should be hot. If only one is, you may need to flush the heater core. Third, if both hoses are hot and you are getting cold air, check the blend air door. It is located near the heater core and based on how far it is open, determines how much heat you get. If it is not working properly, you won't get normal heat or any at all.

first i noticed the heater was not blowing hot, a day later engine running hot and low coolant light on 2 mos ago we had to put a new water pump on and also had to put new lifters in, any suggestions

Hi, Are you losing coolant? Check for leaks. Check the heater hoses, see if they are hot? Check for coolant flow through the radiator?

losing coolant somewhere, filled the day b4 yesterday, maybe 1.5 gallons, its almost empty today cant see any leaks, i did feel the heater hose 1 hot 1 cold

You may need to check the intake manifold gasket for the coolant leak. As far as the heater hoses, maybe the heater core is blocked or a valve that is preventing circulation through the heater core.

I have a 2003 Pontiac grand am replace the thermostat and still no heat need help.

Do you mean no engine heat or the car's heater is not working?
