Air only blows out the defrost?

Okay here is the deal. I just got done replacing my heater core. Everything is back on place and no leaks...

The only problem I have now is no mater what I set the A/C to it only blows out the defrost? Any ideas on what I did or need to check? It was working fine before I replaced the heater core, so it's something I did or didn't do...

check the vacume lines going to the vacume actuator that controls the panel funtionto see if they are kinked or broken they should be blue it think ,

Most likely the vacuum source that controls it was left unhooked. Look around under the dash at the vacuum lines. Maybe it's back not on the back of the hvac controls.

Dang should have done a search first... Looks like a common problem for some after replacing the heater core. I'll check the vacuum lines tomorrow.

Yes, that is baby... Coco, he was 8 months old in that pic. I love labs. Love the color of your pup!

On the issue I have I'm going to check the vac lines tomorrow, I feel like this is my problem.

Thanks!
