In this how to, I'm going to show you what I did to fix my temperature blend door shaft after the actuator sheared it clean off. I do not take any credit for this because I only followed other guides on various different websites including this one, but there were no photos to reference so I'm doing everyone a favor.

This is the temperature blend door shaft that sheared off.

This is when I took the blend door lever over off, got a 3/4 inch aluminum tubing with an inner diameter of 1/2 inch from my local lowes and cut it to 40mm, a packet of jb weld epoxy (the original kind) super glued the sheared piece that was stuck in the actuator still to hold it in place while I went to town on the jb weld lol.

Also, make sure you sand the inside of the aluminum piece that you cut and then the shaft so the jb weld has something to "bite" on to. I used 80 grit sand paper.

And this is with the blend door lever over back on and you can see the clearance is perfect, I tested it this morning and this sucker is never breaking again. I think GM should have reinforced this or something, because this is a very common problem on Cobalts, G5s HHRs and many other GM vehicles.
