Try bleeding the coolant system, then check the hoses going to the heater core, is one hot or are both hot or are none? Post back.

Yes I did bleed it and yes both hoses are hot. If theres away to bleed it please tell me besides the little screw on top of tt. Also when the heater is on it blows the air on the floor.

That tells me that the heater core is not plugged, and that it does not need bleeding. Next check the blend door, can you hear it moving inside the dash when a differnt temp is selected, if the door isnt moving then you wont have heat.

Step 1 - A heater cannot operate unless the engine is full of coolant/antifreeze. If coolant level is low check the system for leaks.
