    Default 1992 Silverado Mode Actuator Linkage

    First of all, in what manual can I find diagrams like this? Bought an online Haynes manual and it had nothing like this:

    When I switch to defrost, no air comes out. The actuator moves and changes between floor and vent no problem, when switching to defrost, there is no air coming out anywhere.

    In the diagram, in View A, take a look at the left linkage of #65. I don't have that. One end of the linkage is still connected to the actuator but the other end is missing and nothing is connected to the post. I'm guessing that missing linkage is what controls the defrost door.

    Now, where the hell can I get that missing linkage?

    PS: Anyone wondering how or why that is missing?!

    Welcome to the forum! OK, I'll bite, how/why is it missing? Dorman has a huge assortment of reproduction replacement parts, you might be able to find one from them.

    Sorry, wish I had a good story for you, but I have no idea. I was just wondering if anyone else besides me thought it was strange that it was gone! It seems like it would be unlikely that it would just fall off with only half of it remaining.

    Thanks for the suggestion. I'll check them out.
