let the dealership mess with it first. If they mess it up, they can fix it. If u do it, and mess up, then you have to pay them.

 

If the door is a curve in the upper part (the frame window) - a small roughness can be adjusted by hand. Put the glass until it stops, open the door. One hand or knee we fix the door open. The other hand, the pressure on the top of the frame. Very carefully to avoid wrinkling the metal. Strong, but short and smooth bumps. Periodically, shut the door and make sure that the curvature corrected.
When my mother slammed the door of her Nissan and left the keys in the car - I arched window frame (the door) through my hands. Formed a gap to the wire probe. I opened the lock through the wire probe. After that I returned to the window frame to place through my hands again.

 

Thats not the problem either. I notice this issue because the bottom corner doesnt line up completely. Almost as if it has a sag. Pushed tight though, everything looks perfect
