Check to see if the heater core's 2 tubes at the firewall are getting hot or not. If not, then the heater core needs to be flushed out, or replaced, whichever is easier (flushing is easier).

Good luck on this repair.

    Ok, thanx! Would changing my thermostat fix this?

    Usually a stuck closed thermostat would make the car overheat. A stuck open thermostat would delay the warming up of the engine's coolant, but wouldn't prevent the heater core from getting hot, eventually (although it may take longer than normal to heat it up).

    A bad thermostat wouldn't explain why letting the accelerator pedal off having a symptom of blowing cool air.

    It could also be a blend door problem, which is vacuum actuated, which can move to a closed position of cool air when the vacuum source changes as the accelerator pedal is depressed or not depressed. But, this may point to a bad vacuum motor or routing of vacuum tubes.

Why would my heater blow out cool air when sitting still and then hot air when going down the road and then it's not all that hot


Try flushing or blowing high pressure air through the heater core lines. its sludge build up and need to be flushed through heater core only. check antifreeze fluid level. only put in straight antifreeze, do not mix. most people do not know what mixture should be, so be safe and add straight, it will not hurt it, i run 100% straight antifreeze and never had a problem or worry about it ever freezing and cracking my block, heads or radiator cracking.

Fiat seicento 2000 reg keeps overheating after going 5 or so miles, light comes on then grumbling and water from expansion tank. had new radiator switch put on, took fan off and tested-works ok- but not...


This may be a puzzle...
The seicento (I drive the same car) likes to create problems in the heater section of the cooling system. The small pipes to it (behind the carburator) may be blocked or the entire heater may simply be dirty. Flushing the system with a water hose may help. Usually this problem starts slowly and goes away if you re-start the engine and then excellerate a few times. Check if your heater blows hot air - if yes, and if he keeps blowing hot air (does not cool down and get cold) ther is no blockage. If you have a blockage, your heater will only blow hot for a little while and then comes normal cool air - if this is the case, you have a blockage right in your heating system which runs your cooling system hot and the cap of your cooling tank will start leaking. This is a comon problem on older Seicentos....
Other general problems can also be the case, like defective thermostat, fan motor does not come on (check fuse and relais first).
In some cases, ther might be some air trapped in the cooling system and doing the above will also cure it. At last, check if your water pump is working.

No heat air is blowing cold


First you have to identify what causes the problem.
To do this you have to:
1) When engine is cold check the level of coolant. If it is low fill it up.
2) Start engine and check if engine reaches regular temperature. If your engine is not heated enough it means your thermostat does not work properly and should be replaced.
3) If engine temperature is normal, then check the temperature of pipes that go to/from heater core. These pipes are located up the fire wall (easier access is from the passenger side). If pipe/pipes are cold (even engine is worm) it means you heater core is plugged and should be flushed. Keep in mind, flushing the whole cooling system is different from flushing heater core.
4) If pipe/pipes are hot/warm, turn off the fan, switch controller to the hot position, wait for 3-4 minutes and turn on the fan. Note if the cold air blows first or warm air blows first but it cools down in 5-10 seconds. If the air blows cold than it is most probably the problem with blend door or blend door actuator.
5) If air blows warm first and then cools down, then while running engine and remaining the transmission in PARKING position, press on the gas pedal until your engine reaches 3,000 RPM. Check if your heater blows warm/hot air. If it does, then your water pump does not work properly and should be replaced. If the air still cold, I would suggest to flush the heater core.

2000 Chevy Silverado 4X4 - Heater isn't blowing hot air


No your thermostat is stuck open which will not hurt the engine. but needs to be replaced, the thermostat is what allows the engine get up to operating temp. before allowing water to flow through the radiator and when it is stuck open it doesnt allow the engine to reach operating temp. so the heater never gets hot. I hope that helps you out.
