To help pinpoint, run your car through a carwash, and crank up the AC. Leaks around the windows will blow bubbles, just like checking for a leaky tire.
The shape of the front windows, is not a perfect match to the door, and you should notice a little bit of bubbling where the window turns to follow the A pillar down. Hope this helps. If indeed that is where it's leaking from.
