Purchased a 2004 SL only days ago and have found that the driver's seat won't do as it should to allow access to the rear bin. Everything works perfectly on the door buttons so there is nothing stopping it moving but when pressing the forward switch on top of the seat it goes forward 6", stops and goes back to where it came from with no movement at all from the backrest. It will be fixed by the seller but it would help if I knew the solution first. They sell quality vehicles and are used to working on all kinds of cars but if they haven't come across this before it may take several visits and they aren't exactly around the corner. Anyone any ideas. (passenger side works as it should) ?
