Window doesn't auto drop 1st time

[rsg26]

Hey everyone 

I recently bought a 2003 350gt and am in love. I'm having an issue on the drivers side door. When I first open the door the window doesn't auto drop. I have to close the door and then open it again for it to work, but the autodrop goes down by around an inch. Way more than the other side. I recently changed the window motor as it was dying a slow death and this issue has been here before then. 

I'm hoping it's just an adjustment issue and wondered if anyone has any tips on how to adjust the window position? It seems to sit slightly low at the front of the window. 

Any help here great fully appreciated. 

Thanks 

Richard
