Location of blend door actuator on a prostar?

[Wolff956]

I work on a Fleet of IH 4400 day cabs, there are three motors, 2 under the dash, Blend and function, with the third under the hood, this is your inside outside air door it uses a different electrical plug than the other two, the one I change most often is the function motor, the plastic sleeve tends to break on these, I recently learned a cheap trick to extend the life of these little buggers, it seems the spring clamp for your 3/8" coolant lines fits these perfectly adding a bit of support the the sleeve.
