blend door actuator

Hey folks !! I'm having a Heater malfunction : My air blend door is not working.The actuator is working fine ,.the servo cycles all the way through.The problem i'm having is that the door is not moving.I have been through this heating system. I R&R'd the t stat,flushed the core, burped the radiator, flushed the whole system .so its got to be the door.Has anyone changed one out before? Did you have to tear the dash out of it? Any Tips would be great, thanks

 

I'm having the same issue with my '00 tacoma. I have checked all of the cables, connections etc. all the way to the heat valve on the fire wall. I am pretty sure that the blend door is to blame, but I don't know how to get to it. Any ideas?

 

Same problem here, i was told by my mechanic i would have to take apart the entire dash to reach the door..
