This morning I went to adjust my seat for my wife in my 2000 Jetta and once I slide the seat forwards, it wouldn't lock into position. The car is a GLS VR6 and the seats are heated with manual adjustments.
I noticed that there is a "pin" that locks into the sliding rack (that has holes in it for each position): it looks like the pin is not popping back out to engage the holes (when compared to the passenger side which works fine).
The system kind of looks like a bicycle brake in that there's a cable inside a housing and when you pull up on the handle to adjust the seat position, it pulls the pin out of the rack. When I pull up the handle I can see the whole housing system compress, so I know that the cable's not broken (and if it was, the seat would be locked into place). I have the opposite problem which is it looks like the pin won't engage the rails and hence, I can't lock the seat into place!
So, I'm guessing that either the pin's jammed (i.e. not lubed enough), or that there is a spring that's possibly broken.
Anyone have any ideas and is this a part that a mechanically inclined guy who doesn't have a lot of experience working on cars can fix fairly easily (like when I replaced my VR6 idler pulley a few months ago with help from an excellent DIY on this site)?
