Showerthought: That weird trick with the door operator on a 90s Otis actually worked.

Got a call for a car that wouldn't level right, kept bouncing at the floor. The usual checks on the tape and the leveling device came up empty. Out of ideas, I tried something an old-timer mentioned once: I slightly adjusted the spring tension on the door vane cam, just a quarter turn. The bounce was gone and it's been smooth for a week now. Has anyone else had to mess with the vane cam to fix a leveling issue?

You actually messed with the vane cam spring? I was always told that was a last resort fix. It's wild that a quarter turn solved a bounce like that.

My old Ford needed two full turns on the spring.

Yeah, I get why they call it a last resort. On my truck, the bounce was so bad it felt like the whole dash was gonna shake loose. A tiny adjustment made all the difference, but I was sweating the whole time I had the cover off.
