I've just been checking over my roof as its become a bit slow/noisy opening and closing.
Read though all the posts here and checked the cables etc and everything looks fine. I seem to have the newer cables with the re-inforced housing but also have the older red plastic balljoints.
Nothing was broken and I checked the length of inner cable that was inside the motor and again plenty there.
But I seem to have a problem with the clamshell cover being slightly offset to one side, which causes a slight problem when closing, leaving one side very slightly high and requires a gentle push
