Default changed blend door acutator still all hot air

I changed the blend door acutator because I had all hot air or all a/c. That didn't solve the problem. I still have all hot air. The blend door moves but it is all open or all closed. Any suggestions on what I should try next? The door appears to be vacuum operated. Is it necessary to replace the cylinder that opeates the door? Any suggestions are appreciated.

Blend door is operated by the electrical actuator, not vacuum. Verify that the (electrical) blend actuator moves with the power on and when you rotate the temp knob. If it does, you have a problem with the blend door itself, if it doesn't you need to trace an electrical issue.
