If you changed any parts in your cooling system, you probably have an air pocket in your system that will need to be bled out. This is why cold at heater. If you did not change any parts in your cooling system, and you are filling system with antifreeze, then you have a leak somewhere. Have you noticed any anti freeze under your car? Look under front of car below radiator, under water pump side of car, check for visible leaks hoses under hood. Only you know for sure what's happening on your end. GOOD LUCK FRIEND.

There are many reasons that this may be happening. #1 Heater core may be plugged up. #2 Blend door actuator motor may be bad. #3 Thermastat in coolant system may be stuck open causing the engine to never fully warm up, thus causing your heat to never warm up.

you have to change your Heater Core. Your Antifreeze moves in a circular motion from Radiator to Thermostat through engine to your heater core back to your radiator. If there is no circulation, your engine is going to overheat. I had the same problem with my Pontiac Grand Prix.

sounds like a stuck thermostat. but check if the system has a bleeder screw if it does burp it and that will help also.

Okay. warm up vehicle, get radiator hoses hot.  Turn on heater, fan on low.  Grip both rubber heater hoses close to the firewall, from the engine compartment side.  They should be too hot to hold for long.  If they are not hot, then you have a lack of coolant circulation to the heater hoses.  If they are hot then access heater core, behind glove box area.  Blend door which moves as you chose HOT or Cold, should be cable controlled, move the controls and be sure the door is actually moving. Keep me posted

SOURCE: 2000 Grand Am overheating and inside heater blows

Dear tnevilcat,

You may just need an engine thermostat!

The hose coming off the coolant surge tank doesn't attach to anything! Yes they all just pour the boiling fluid onto the road!

If you think you got a raw deal....go right to the dealer you bought it from and if they laugh...

Click on the following link and do a little investigation....What happened to you is just not right!
http://law.freeadvice.com/general_practice/lemon_law/lemon_law_used_car.htm

What state are you in? Different States have different laws! Check google.com for your States "Lemon Law Used Cars Your State".

Did you get a written warranty? It may not matter!

Get back if you need more help!

SOURCE: Car Heater Not Working - Blowing Cold Air

also check to see if tube that runs your climate door is not pinched or broken. the vaccum tube that runs the climate door is behind and under the battery. i had same problem a year ago and the tube was partially cut. i fixed it by cuttinga piece of aquarium tubing and spliced it back together. one other thing.....check to see if your radiator over flow cap is tight. your cap maybe bad and or cracked this would also cause the problem.

In 2005 chevy impala the heater only gets warm sometimes. Other times it blows cold air. I put fresh antifreeze in. And there is no water on the floor of the car


The adding adding coolant means you have a leak somewhere, and low coolant level will cause this. How often do you check the fluid levels? Check for leaking hoses, weak radiator or expansion tank cap, leak at the water pump, and leaks around the radiator.

Thermostat problems


your easy, that is caused by AIR Pocket in the engine block
the gauge can not read, air temps so if air is below the engine
coolant thermostat the ECT reads hot then air (cold ) repeats
you lost coolant and the number one reason for that is trusting
the silly side tank, (they fail easy)
never do that, on the next cold morning , dead cold
you take off the RAD cap. look down the neck, is it full of green
AF? id bet you its not.
the cab heater will never work with no engine heat, ever. so ......
never do the above on any hot engine.
also the thermostat might be bad and the coolant overheated
and blew out, so get a new STAT.
the flush the system, and refill with 50% AF.
or worse. lots of ways to overheat.... ask.
the side bottle only works, (called the expansion tank)
if never overheated
and the tube in side is not dropped off
and you never let it go dry, ever.

those facts and others are why we check the RAD directly cold.

Heater works while car is at an idle but not while driving


The expansion tank/coolant reservoir is supposed to be vented at all times. You should not have to "bleed" air from it. Your coolant is not circulating thru the heater core because of this and you continue to have this problem if its sealed. It may even explode from the coolant being hot if not vented. Once it's vented, just top off the radiator and fill the reservoir over half way or to a mark that should be on it then drive it around. Keep a check on the reservoir coolant level and keep it half way up and you'll be fine.

2002 Caravan,3.3 V6,FWD,had a loose rad cap and lost fluids till no heat in heater.Replaced cap,filled overflow reservoir,ran for a few kms,refilled tank.Still no heat unless motor revs,all levels are...


You still have a lot of air in the cooling system and you have to speed up the water pump to get any coolant to flow through the heater. Let the engine cool off, then open the radiator cap and top off the radiator. Pour the coolant in at a rate slow enough to let the air bubble up without splashing the coolant back out. Once you get the coolant level up to the top overflow hose, the remaining air will be pushed out by expansion through the overflow tank once the engine gets hot, and will be replaced by coolant from the tank on cool-down.

Heater is blowing cold air,


Check operation of heater coolant control valve, and it's associated remote control mechanism.
Check that both inlet and return heater hose is equally warm, as this indicates coolant flow through the heater core.
If no coolant flow:-
Check cooling system is correctly filled, taking care to bleed off any air locks from the system as necessary (with heater coolant valve open);
Check heater core is not blocked.
