While vacuuming my 1996 Collector's Edition I discovered that the driver's side seat cushion was not fastened down or inserted tightly. I was able to easily lift it up and look underneath at the power controls. The passenger side was snapped down properly. I also did not notice a snapping mechanism that would fasten the seat. Is this normal on the driver's side or is something missing? I would prefer that the seat snapped down tightly! If it is not normal, what do I need to do to get the seat to fasten?
