My rear passenger doors always have at least a quart of water inside them every time it rains or if I go thru a car wash. My window wipers are installed tightly onto the pinch welds and seated properly. There is no room to drill drain holes and keep the water outside the door seals. Anytime I open the rear doors, they will leak water for at least 10 minutes. What can be done to fix the problem?

There should be drain holes in them from the factory. They may just be little upright slots in the edges of the bottom door edge. Check them and be sure they're clear.

There are drain holes, do note that if you get rust coating done that the fluid will swell the rubber seals.
I mention this because multiple times I have run into this. Vehicle gets rust coated and the rubber swells blocking the drain holes.
Look at the base of the doors where the rubber goes across the door. The drain holes should be at the base of the doors

There are drain holes. They should be at the bottom just above where the lip of the door skin folds over the door shell. Sounds like yours are clogged. The belt molding (what you called a wiper) is not there to be water tight. Water does get into the door no matter how tightly the belt molding hits the glass. The belt moldings main function is to cover the top edge of the door window opening. It’s secondary function is to keep some water out of the door but not all of it. You may need to remove the door interior panel to clean out the bottom of the inside of the door shell. But usually inserting a piece of mechanics wire up through the holes and moving it around is sufficient to get the drains flowing more freely. But if there is a lot of gunk in the shell it will clog again shortly.
