Mine kind of gets stuck sometimes. After a while, it stops going up when I turn off the car. I am not sure why, but I just keep pressing up on the lever, and it seems to reset / loosen it up. I don't know if the gaskets or whatever get tired, but it seems to get tight.
When I do press up, the wheel barely moves the first time, barely moves the second, moves a little the third, and the fourth it regains full movement. Something like that.
I hope this helps. It is hard to explain myself first thing in the morning. Oh, I don't think it ever had a problem with going down, just going up.
