    10 amp Fuse # 24 in power distribution center !
    Try This!~!!
    If it don't work take a couple shots of Te Kill Ya and call me in the morning!
    Just j/k!~!!

    We will try something else!!
    Re-Calibrating Actuators




    Use the following steps to perform the calibration update:
    1. Turn OFF the ignition. Remove the battery positive voltage circuit fuse of the HVAC Control Module.
      Important

      The module memory will not clear if the battery positive voltage circuit fuse is installed in less than 60 seconds.

      Wait 60 seconds.
    2. Install the fuse.

    Default Oh man,I screwed up.................................

    I gave you the wrong fuse and location!

    Won't hurt anything,Just the wrong HVAC fuse.

    The fuse your looking for is in fuse panel under the passenger side floor panel!
    Just lightly pull the top of the floor panel back and slide up!!
    Black box underneath and remove the cover!
    Fuse #18 (10 amp)
    What we are wanting to do is make the HVAC controller loose it's memory and reset it's self and all the actuators!~!!
    Sorry,Thats what I get for having 9 service programs running at once!~!!

    I wouldn't worry about the check valves much on a C5 there away from the engine heat under the finder with the vacuum reserve tank!C3's and C4's were on the engine and went bad purdy often!

    How many vacuum lines did you have to repair,usually the one from the vacuum port on the engine go's bad,but any of the 3 will scramble the HVAC Controlers Brain!~!! So it needs to be reset by killing the power to it!~!When it resets,it fully swings All of the Actuators and brings them back to center,so the HVAC Module knows where there at!~!!
