You have air in the system. You have to park the car on an incline so the front of the car is higher than the rear, then run the engine with the radiator cap off and let the air escape while topping off the radiatorevery now and then. I was told about the incline to get the radiator higher than the heater core so that the air bubbles could come out.

The heater core may be stopped up.Remove bothe heater hoses from the heater core,and use a water hose to flush out the heater core.Put the water hose up against one heater core pipe,it will come out the other pipe.Make sure the vent door inside the car is moving when you select heat,If I can help,any further,please let me know.>>[email protected]

There is several ways to see. 1. It could still be the heater core, try blowing air in to IN house, if it comes out the OUT hose strong, its not that. 2. It is posible there is an a pocket in the system. Try bleeding the air hose, that could be it. 3. Take the glove box out, disconnect the air bag CAREFULLY! Start the car, And turn the heat all the way up, then all the way down. U should see a arm move back and forth. MAke sure it goes ALL the way shut, and open. 4. It could be that the doors in the dash don't work. I'm not sure how to do this. Hope the other work!!

tear the dash apart and replace or have some one else do it if tearing the dash apart doesn't suit you
Air
Temperature Control Blend Door Failure
In
all modern cars there is a tiny DC electric motor driven gear drive
that moves a plastic door that blends heated and cooled air from the
AC and the heater core, this is called (interestedly enough) the air
temperature control blend door actuator. The motor that moves this
door fails because the door starts sticking from warping, most common
complaint is no heat but it can be no AC as well. To replace these
parts (blend door and blend door actuator) you must remove the entire
dash from the car. Always have this problem confirmed by a dealer or
qualified repair shop as it is a very expensive repair.
