Default Just changed heater core, Now a problem.
I just got done changing out the heater core, accumulator and evaporator on my 99 Dodge Ram and now when I turn the heat or a/c on it will blow through everything but the front vents.

It will work on the floor and defrost settings only.......Any ideas on what to check? Check valves?

I don't really want to pull the dash out again....lol

did you disconnect any vacuum lines under the dash?

I think you have a problem with one of the actuators. Either you didn't hook up the vacuum line or the diaphragm is leaking.
