For a couple of years now since my re-spray i have had slow, lazy windows. They are fine going down but on the way up they can sometimes struggle. The worst is the drivers side which sometimes stops about an inch from the top. I have had the door cards off and adjusted them every which way to ty and improve them with no luck. I presume they are rubbing against some rubber parts, as the drivers has a fair few vertical scratch's on the glass, which is slowing them but cant see how i could fix this. Could it be that the motors need replacing or all new rubber peices etc?
Anyone else had this problem and managed to fix it?
