No movement at all when you turn the ignition on in the dark? Silly question number 1: they are factory fit aren't they, with washer jets underneath!? I would've thought that after removal they would revert to their previous settings, so would still self level?
Edit: When I replied I assumed you'd picked up a new (to you) car and this was a pre-delivery task... but re-reading it I don't know why! Presumably they were self levelling before they went in then!?
