Ok.. either you have not "bled the cooling system" or the blend door is messing up
To "bleed" a cooling system on this car.. fill it up, leave the radiator cap off and run the engine with the heater on high.. once heat comes out (the top radiator hose and both heater core hoses will become warm at this time also) it will have been bled.
Also sometimes , a little motor called a blend door actualtor fails and can cause all cool or all heat from where the motor fails.
If the top radiator hose and the heater hoses are hot but car still ain't , I'd look at a motor (blend door) if not, it's time to check for bleeding (air pockets) and /or blockage

There is a valve that controls flow of coolant through the heater core. If this is not working properly you will not have heat. Some of them are controled by vacuum and others have a solenoid. You can find out which in a repair manual. You may also have a problem with the control unit in the dash although this is not common it is possible.

Check the Heater Control Valve.

You probably have a hot heater core, but the vent control system is bad and you're not getting the air through the core.

Is there sufficient coolant in the system? That's the first thing I'd check.

it may very well have an airlock. run the car at 2000 rpm making sure the engine does not overheat
