Lots of thing, this happen by random? or it leaked out or doing service.
1: thermostat bad or installed backward or jiggle pin not UP hill.
2: air in the block, never burped during service.
3: pump impeller fell of, or rotted off.
4: fan belt missing or loose.
thats about it.

SOURCE: Heater blows cold air when idle

Sounds like you may have a partially plugged heater core. You could flush this out separately, from flushing radiator & engine block. Diconnect heater hoses going to your heater core and clamp off, so not to loose coolant from engine. Now hook up separate hose to one side of heater core pipe and flush out with typical garden hose. Repeat procedure on both heater core inlets. Reconnect original heater hoses and test difference. You may have to add an additional litre of antifreeze. If this don't work i suggest changing heater core. Good luck.........Ron.

I have a 2002 grand cherokee I put freeion in the thing and it stills blow hot air. You have to take a stick and push the clutch in then the compressor runs .but still blows hot air out.The gauge says it...


Do this:
When the vehicle is COLD, start it and start the a/c and see if it is cold then. If so, your heater temperature controller is stuck in the HOT position. Check the hoses going from it and if this is true, replace the controller. The a/c is running, but the controller is sending hot water to the passenger compartment heater radiator.

Heater and defroster blowing cold air


Check your antifreeze. Then thermostat. If the engine is up to operating temp. (hopefully not overheating) and your getting no heat then you're most likely not getting the coolant to circulate. Either thermostat not opening, heater core bad, clogged radiator or coolant system.

Does your temp gauge read normal? if it does then the thremostat is ok,but sadly the water pump is going bad this is typical of jeeps at an idle the heater cools off because the water pump fins are worn enough to not circulate through the heater core and when you step on the gas the increased rpm move the water fast enough to circulate through the heater,it is possible that the heater core is plugged but I doubt it as a plugged heater core would not get hot either it would be cold or just luke warm all the time.
