Thanks for your reply!

I had a similar problem, mine wouldn't close the last 1/4 inch. When you get the mechanism apart, there is a central motor with rack and pinion gears that move the spoiler up and down by pushing cables through upright tubes. If the gears are stripped, those aren't sold separately, so you'll need to buy another mechanism. Taking it apart is pretty straight forward, but getting it back together is much harder, but doable. If the gears aren't stripped, clean the grit off the tubes and cables and re-lube them with some new grease. The ends of those cables have springs on them that go into the rack gears. Getting them back in and keeping everything together is the hard part. I found that using my workbench with the gear against the base of my 5 inch vise bolted to the bench, I was able to compress and push the springs back into the gears. Then you have to carefully place the gears with the springs and cables back into the mechanism. There is nothing to hold the springs in place, they are held in place by the sides of the mechanism case. Wear some heavy leather work gloves while you're getting the springs back into the gears, they have sharp angled metal on their ends and you'll cut your hands a lot if you don't. I figured that out after only a couple of cuts!

I hope this is helpful, good luck!
