Window power down problem
 

Hello. New to the site. Hope someone can help me with this problem. 2001 slk320 passenger window won't go down all the way. About 1/4 inch of the glass is still visible above the door when powered all the way down. How can this be fixed? I was told its a programming sequence done thru the power switch but I can't seem to fix the issue. Any help is greatly appreciated!

it's not the same as the drivers side? normally they don't go all the way down. there is a portion of glass that does show above the door. should be the same on both sides.
