Heater core hose heater adjustment arm

Can anyone help me out with the heater adjustment arm in the little snapping that goes in to hold it? Mine is broken and the arm is gone and he both replace it because somehow when I was messing with it, I got a leak and I fix the leak, but I just need the parts to get it to work again, please let me know

Do you have a picture of the part you’re looking for? I’m not sure exactly what it is, because I haven’t had to mess with the heater core.

Are you referring to the spring clip that holds the cable in place?

No it’s the litttle metal arm that has threads on one end that snaps into the lever that moves the door from Heat to Defrost it’s the arm that the cable attaches to and the arm moves the door up and down inside the heater core, sorry that’s about the easiest way I can explain it and I do have a picture of it. I’m just don’t know how to add pictures on this site. UPDATE : it looks as though I was able to upload a couple of pictures if you can see the black arrow pointing to the little metal rod inside the yellow circle, thanks to anybody who can help me with this part.

Now days they would call that a blend door actuator.
