[Alpines] Window lift

Lauri,
 
The window channels are different sizes between series, ithink pre SII and  
SIII on. You may have used parts from different series, e.g with rollers 
too  large for the channel. Is that possible. If not, it may be the side 
channels  need moving in a little to avoid catching. Also try a little silcon 
grease on  the side channels, and plenty of regular grease in the bottom 
channel under the  glass.
