I have a brand new window regulator button but it wont stay on. How can i solve this problem.

Another problem I have is that both of my windows get tighter as i roll them up, meaning the higher the window gets the harder it is to roll up. Any help would be greatly appreciated, Thanks

Talk to 914 rubber on what happend to your button, maybe you need another maybe it is buggerd...

As for the tightening window, you need to re-adjust. I assume you have your dooor panels off so you can see all the adjustment there, plus the ones under the door.. not fun ever as it seems to go from one small issue to the other until you find the medium, though it can be dialed in... it will seem like hit and miss for awhile..semi-logical one adjustment at a time.
