Aerocab drivers side door leak

[Matt]

I've got a 2008 T660. The drivers door leaks air quite badly. It's coming in right on the edge of the door at the bottom right corner (if you were viewing the door from outside the truck). Replaced the primary door seal because it was cracked and torn but yet when i look down from the inside at that corner I can see daylight. No air coming from any other part of the door. Is there an adjustment I can make to get this thing to seal again? Feet get awful cold in any sort of crosswind blowing into the drivers side of the truck.
