Heater and A/C vent control

[SCHTLH]

I am new to the forum and am hoping someone can help me. I have a 2001 Ram 1500 that I just changed the thermostat and flushed the heater core. After I was done and started the truck the vent control does not function, the air goes to defrost and the foot. I can not figure out what I have done, I would appreciate any help.

Check for loose wire on dash control and also check all vacuum lines.
