This is most likely due to an empty cooling system. Check the coolant in the radiator (with the car off for atleast 30 minutes). Once you refill it you can see if you have a leak in the radiator or a hose, etc. If there is a bunch of smoke coming out the tail pipe or the oil level is really high, than you have blown a head gasket.

Only get cold air from heater


Check whether any hot water flows in the heater hoses which are located between the engine and the firewall .If you to have the feeling hot water and not hot air in the cabin means either you do have blocked Matrix,or the circulation flow valve stuck to cold flow.
* Start the engine first and leave it for 5 minutes running till get to temperature and then check *

Why Is My Heater Cold?

1999 Chrysler 300m heater won't get hot fan blows but doesn't heat


Is there enough anti-freeze in the system?
If so perhaps the system needs bleeding.
On the front of the engine, on top near the big upper hose goose neck and nestled between the runners of the intake manifold is a small nipple that looks like a brake bleeder (10MM). This is a cooling system bleeder, a close cousin to the brake bleeder. When opened it will purge the system of air- likely the culpret you are experiencing. on a cold or just warm engine, this can be slightly opened with a wrench and the air can be "Burped" out. Attach a 1/4" clear hose to the nipple and open the bleeder until you see all the air has left the manifold. (Run the hose into a bucket and dispose of the used anti-freeze properly.)
if that doesn't do it, maybe the thermostat is stuck in the open position. Replace it with a cold engine and use a new gasket each time.
If all else fails, the heater core may be plugged.
