I have two rear seat problems . One is well and truly stuck in place (I have tried, along with another forum member all the tricks). The other seat is out but the mechanism seems jammed in the normal position when in place! So I am trying to work out how the mechanism actually operates - I have found that you can pull off a part of the seat cover which gives a little access to the rod and the ends that the handle connects to. But whilst I can get at these I cannot see enough to work out how it is supposed to work. What would really help is a diagram of the mechanism and some clue as to what is supposed to happen when you lift that handle at the rear base that should lift out the seat. it seems to pull on a rod such that the rod would twist but how that releases the seat and how it locks the back closed against the seat is not obvious.
