Heat air mixture.

I new here. Enjoying all the info so far. I just bought a 1986 cab in chassis k30. Love it. But had no heat. Took off the cover under the dash and found the tab hooked to a spring on the mixing door broken. I'm gonna order a manula soon but was wondering if anyone had any info on this part. I'm not even sure what to call it. Thanks for any help.

That's the blend door and I don't believe the broken part is available anymore unless you find a used one. The last broken one I had I repaired with some sheet metal by making a splint for it that used the original screw.

Lots of info here:

Kinda was what I had in mind. Just figured before I mess with I'd ask. Thanks for the info.
