I dont know. I know it's a complicated system with 4 separate hydraulic
circuits, limit sensors and logic in the circuit itself. My problem was hydraulic
so it just wouldn't go up all the way and it wouldn't go back down....all the
subsystems got screwed up at that point. I think that if it is eventually going
up or down for you it's not a hydraulic problem (leak). It sounds more like a
slightly flaky limit sensor and pressing the button again resets it. I would bring
it in and just pay for an hour to get them to run a diagnostic on it. If it's
just a sensor that needs to be replaced it might not cost that much. As I
mentioned previously, if you have the extended warranty the roof is covered
....believe me, I asked before I plunked down the $6K plus a B-Service for it.
