1985 buick lesabre collector edition door adjustment

I have a 1985 buick lesabre collector edition that I would like to adjusted the doors on to perhaps contain a water leak problem when it rains. I have replace all trim around doors, but i think the problem is that the door is not sealed enough...so i would like to know which bolts do what on the door as for as adjusting it. (Driver and passenger side) Thanks in advance for the help
