Help! Installed window tracks, regulator and window in drivers’ side door with ease-works great! Passenger door different story! This window did not work properly before we began restoration. I got a new regulator as I thought this was the problem. No matter what I have tried- the same problem occurs-the window rolls up straight but as you roll it down the front of the window somes down further than the rear. Any advice will be appreciated.
It sounds to me that the tracks or guides are not aligned properly.In this case it would seem the front track is out at the bottom mount.As the window goes down the bottom of the window is allowed some movement and the window is slightly tilted.There is some adjustment at the bottom mount but not much.You may have to elongagate the the holes in the bottom mount.
