About to add a/c to my non-a/c truck this weekend, and I wanted to confirm the blend door operation before I get everything in and find out there is an issue.

Is it normal for this door to sit in the "middle" position when disconnected? I'm assuming it's because there is no vacuum being applied to either side of the actuator at the moment (where in operation it would have vacuum applied to one port or the other holding it in place), but I just wanted to be sure. I can manually push the lever to either side, and then it returns to its resting point in the middle.
