The thermostat and radiator are part of the engine cooling system, not part of the air condition system. Chances are, the A/C system is low on refrigerant. The system has a low pressure switch that prevents the air conditioner compressor from being damaged with the Freon is low.

You can purchase a can or R134a refrigerant at any parts store and try recharging the system yourself….the basic instructions can be found here:

Heater isnt blowing warm air in 2003 grand caravan


Assuming the radiator is full of coolant, you are describing a faulty thermostat. The thermostat is closed when the engine is cold to restrict coolant flow until it warms up.

Won't blow hot air, engine heats up at high speed


If your radiator is full of water, then its probably the thermostat sticking. The thermostat is located on top of the engine, under the housing that the radiator hose goes to

replace any soft hoses.
collapsed hoses cause water flow constriction
.that increases temp fast

to bleed air out of the system . if no air bleeder as such
with heater on full .-engine running
loosen the bypass pipe for the closed thermostat till only coolant flows no air bubbles
check if

My heater blows cold air when car is stopped. i have installed a new water pump and the radiator is full of water.


you still have air trapped in the cooling system. Get front of car as high up as you can on a hill. Cold engine - loosen radiator cap, fill with 50/50 antifreeze mix. Start engine and run until upper radiator hose is hot (thermostat open). Engine should burp air and maybe spill some coolant, that's ok. Once burped, tighten cap, shut off engine and let it cool down while keeping the reservoir full. It will **** coolant out of reservoir as it cools. Keep it full.

If still cold air, take to a shop that has evac/fill equipment; they will **** air out and repalce with coolant. About $80.

My heater starts heating & then it suddenly quits & starts only blowing cold air. Is my heater core also clogged or is it something esle?


I'm thinking your cooling system has air in it. If you have recently drained and refilled the radiator, then that is probably what's wrong. I'll be brief, and tell you how to get rid of the air. Put the heater control on hot, fan off. Remove radiator cap. Start engine, let it warm up. Watch the coolant level in the radiator, when the thermostat opens the coolant level will drop. Add antifreeze to bring it back up to full. It will drop again. Add more antifreeze. Continue to do this until the coolant level no longer drops and the coolant is flowing good. Put the radiator cap back on. and see if the heater is working better.

Hi, i have a 1992 honda accord aerodeck with the 2.2 efi engine.. My problem is that i can only get cold air :( even when the knob is turned on full wack to hot it still only blows out cold!! I replaced...


take the radiator cap off when the engine is cold check the fluid in the radiator,if necessary add fluid to the radiator not the resevoir with the motor running and with the heater on until full leave the cap off untill the motor gets up to full heat and the thermostat is open and pulls the fluid into any unfilled cavities. Add fluid as necessary.

The heater will not blow warm air until you start driving. The fan blows but its cold air. Once you start driving the air turns warm. Why?


There may not be enough coolant in the system. What happends is the heating core is nothing more than a small radiator inside the car. If the fluid is low the heating core is empty. But once you start driving the water pump works harder and fills it up. Another possible cause is a sticking thermostat. If its stuck open the engine cant retain water to heat it up. Thus blowing cold air. Whith the engine cold remove the radiator cap and check your coolant level. If it is full a replacement thermostat may be needed. HTH and dont forget to rate.

The heater does not blow hot air just cold air all vent controls work.if running air conditioning can control temp with the hot cold control


The first thing to check is the coolant (antifreeze) level in your radiator. If this level is too low it could cause your heater not to blow hot air. Check this when the engine is cold by removing the radiator cap. Do not remove the radiator cap when the engine is hot. If you do, you run the risk of getting scalded by hot water and steam that can shoot out the top of the radiator. The radiator should be completely full. If it's not, fill it up with a 50/50 solution of antifreeze and water. Also make sure the radiator overflow tank is filled up to the full mark. This is usually about halfway up the tank.
If your coolant level is ok I suspect you may need to replace the thermostat. It may be sticking shut and not letting hot water get to your heater core, or it may be sticking open and preventing your engine from reaching its normal hot operating temperature. A thermostat is relatively inexpensive and usually easy to replace. Just make sure you follow the instructions and put it in facing the right direction. If the thermostat is ok then you may have a blockage in your heater core. Replacing a heater core can be a difficult job on some car. If this is your problem I recommend taking the car into a garage to have the repair done. I hope this helps you out.

Did you open the radiator cap and make sure the radiator is full of coolant? Sometimes the hose from the coolant reservoir to the radiator becomes plugged, and the radiator will become low on coolant even when the plastic reservoir is full. Low water levels will prevent the coolant system from getting hot water from the engine to the radiator or heater cores. This will cause the engine to run hotter while the heater appears to not be working.
