SOURCE: Engine running hot

Sounds like your antifreeze level is low. When it flows you get hot air and when there's an air bubble due to lack of antifreeze all you'll get is air.

The Idle Air Control valve might be bad and may need to be replaced. It should be located on one of the heater hoses. You can take the cable off and move it one way or another to see if it will get hot. If it doesn't then it should be replaced, or the heater core might be clogged.

SOURCE: Heater blows hot air while car is moving but cold

That sounds like the coolant level is low. If it is not the use of "stop leak" has probably caused a partial clog which restricts the flow of water unless the vehicle is turning higher RPMS. While sitting still raise the RPMS to about 2000 and see if the heater blows hot air to see if the above mentioned problems are fact.

Heater not warming up


Most likely the thermostat broke. I expect that you have an older Hyundai and never had the anti-freeze changed. When the engine is cold the thermostat is closed which causes the engine to warm up more quickly. A warm engine runs more efficiently (less gas) and more smoothly. When the engine temp reaches a certain temp the thermostat opens and then allows the hot engine coolant to run through the lines to the heater core. The heater blows air over the heater core which produces the warm air that warms up the cabin. Thermostats used to be cheap and easy to change. I would suggest a web search for how to replace the thermostat. Something like 'hyundai accent 2002 replace thermostat".

I have a 2002 Chevy tracker. It's been running hot on the temp gage. So, I have changed the thermostat and replaced the radiator hose because of corrosion but it still overheats and when I turn on


If there is cold air coming out the heater than there is air in the system. After you replaced the thermostat did you run the engine at idle with the radiator cap off until the engine came up to operating temp? Doing this will purge the air from the system.

No heat after warm up, need to change Thermostat


If your car is otherwise running fine, then the thermostat is doing its job and replacing it is not going to fix your heater. Either your heater core is bad or the mix flap which allows cold air into the hot air is broken. I would take it to a dealer and get their view and estimate, if they tell you they want to replace the thermostat, take it to another dealer.

Tempeture guage not working and heater is blowing out very little hot air on my ford galaxy


you need to get the thermostat changed. The thermostat controls how much coolant runs around the engine and sends signals to your temp gauge to indicate how hot the engine is.
if the thermostat is faulty it wont sent signals to the temp gauge and wont open up to allow coolant to run around the system. Your heating is run by coolant, behind the dash there is the heater matrix hot coolant runs into the matrix which gets blown inside the cab.
Fitting a new thermostat will fix all the heating and gauge problems. if your technical minded you can buy a thermostat from an autofactor (or ford, but they are expensive from ford). a garage will charge about £30-£100 ish for a new one.

hope this helps :-)
