No Heat!!!! WTF!

[Myco]

I just put a new heater core in. Hoses are connected via:

Hoses get hot, ac works fine, blend door moves (I can watch it move) air comes out the dash fine.. switches between vents fine. ... what's going on here?

Anyone have any ideas?

TO NOTE: I haven't burped the car yet.

I let the car idle for 20 minutes then drove it 2-3 miles. I figured that would get heat out the vents... it IS 40degrees outside though...

I'm stumped.

Then put your helmet back on and go back to your coloring book.

same problem with my car but some time's the heat worked most time it did not.
but what i did was changed the thermostat, and at first the heat was still comming out cool/cold so i had to keep adding radiator fluid untill the car stop gulping it, but it worked so try that make sure your fluid full for the heat to work right
