I have a problem with no heat replaced the heater core and the blend door now I have no heat one heater hose is hot and the other hose is cold so there must no be water flowing through heater core but I don't know why. I've tried to bleed the system several times and thought I had it. any ideas?

 

Gotta be a valve isn't opening, or still air in the system, IMO.

broken temp control blend doors inthe hvac case are common....check to see if the door is moving when the temp control is changed.
