Is there a way to lube the AC controls? The Z is giving me much more resistance than the Coupe when I turn the knob to change the flow to the floor vents.
Ron, do you have the official BMW docs on this by chance?

I believe it has something to do with the wires and not the knobs. Just like Ron, I remember reading it somewhere here. I can't find the thread anymore:dunno:
The cable seems to be sticking at each position, but I don't really see a way to replace it. It is riveted to the AC box.
Following the link above I am adjusting the blend door knob. I have a spare AC panel (all you guys who made fun of me for stockpiling parts feel stupid now!)
I ended up drilling and tapping the lever arm for a servo ball joint that was recommended in the other thread.
As best as I can tell, the blend door is sticking inside the AC box. Moving the lever by hand gives me the same resistance right before it lets go.
Not sure I have a better solution, but the ball joint works well and the AC is working again.
I have a pack of the joints, I also have the drill and tap kit I got for this project. I also picked up a drill press to make sure I do it right. And a set of mini wrenches.
So.... if anyone needs this fix, just let me know and I can probably do it for you in a few minutes.
