If there is a internal antifreeze leak, there will be antifreeze mixed in your oil. Check your oil. If there is antifreeze in there, you probably have a bad head or base gasket. Worst case scenario is your block is cracked somewhere. Check your heater core and the lines as well. If the heater core is bad it will be leaking.
Check the thermostat housing for a leak. Sometimes
the antifreeze will leak from there, and burn on top of the exhaust instead of dripping onto the ground. Good luck

Heater blows cold air

Sounds like the cooling system is low on antifreeze. Have you checked to make sure it is at it's proper level?

Not Overheating, Smells like really hot antifreeze after I drive, a/c ok heater heats but when stopped air gets cold...stummped..thermostat?, Leak?

check your hoses and make sure its not getting low because when it gets low the hoses can get hot enough to expand and spit out antifreeze without overheating

Antifreeze leaked out overnight

So you are saying you'll have to find the source of the leak ?
The cooling fan would come on when the computer can't get a signal from the temp sensor. And the heater would blow cold if the coolant level was low.

After 40 mile ride engine started to overheat. Heater blew cold air.

when the heater blowes cold you are low on anti frezze, the system is designed so that when the system gets low on coolent the heater will blow cold it is a waning for you to know some thing is wrong, i dought it is a head gasket but it might be, you need to have some one pressure test the cooling system, my first thought is to have someone take a close look at the weap hole on the water pump. we see alot more waterpump leaks then head gaskets on the jeeps.......good luck

I had heat blowing out now cold is blowing out of my 2000 maxima when the car is warm i turn on the heater cold air blows out

check you antifreeze level, if its low you may not get any heat. other then that it can be vapor locked (not great if it hasn't been emptied and refilled recently , could be a bad head gasket) or it can be the control in the dash...if so you may hear what sounds like an air leak(losing vacuum) or the air doors may be stuck towards the cold.......I hope your antifreeze is low, the other things are a pain to fix usually

Heater blows cold air when the truck is idling or in stop and go traffice

a question to an answer: is your truck has any heat when you rev it 2000 rpm, or above?
have you check your coolant level? if level is low you have a small coolant leak, a water pump may be at fault, and causing air pockets in your heater core, check for leaks your self, dealer wont tell you if vehicle still under warranty.
good luck

Teperature gauge running hot and heater not working

If the car is hot and the heater blows cold air your thermostat is stuck shut or your radiator is really low on water/antifreeze check when engine is cold hasn't been ran like overnight take off the radiator cap and if it is low add so antifreeze/water if heater still blows cold air or water level is ok your thermostat is stuck shut and needs to be replaced.

My heater just started to blow cold air, what are

first likely problem is low antifreeze. If there isn't enough, it can't fill the heater core. wait til it cools down - about five minutes in this weather ;) and then open the radiator and fill it with antifreeze/water combination. If it takes a bit (more than a few pints, then you might try adding some Bars leak or radiator stop leak junk.

If radiator is already full then you probably have a blocked heater core or a stuck thermostat and will need to take it in.

Check your RADIATOR. it probably has a leak or crack or both..Well, i guess if its leaking it must have a crack. This is most probable to your problem affecting the air cold to hot vice versa.
