On the passenger side getting wet at the door, first check the drain holes in the bottom of your doors. Make sure they aren't clogged. If that happens, water can build up inside the door itself.
Now, open the front door. Check for Stink bugs wedged in and around the weatherstripping. Yes, these nasty buggers can cause leaks! Been there. . .
Next, carefully remove the weatherstrip around the door opening in the body (it just pulls off). Be sure to go all the way around. The weatherstrip has metal inside so it can grip the pinch weld in the sheet metal around the door opening.
As you remove the weatherstrip, check to make sure no portion of it has been pried or left open in such a way that it won't have a tight grip on that pinch weld. Also check the pinch weld itself for metal burrs and remove those with a file (they can keep the weatherstrip from sealing properly). If you scratch through the paint while doing this, be sure to touch it up.
If any portion of the weatherstrip was pried open, gently squeeze it closed again with your fingers. It should be open just enough to fit onto the pinch weld but no more.
Reinstall the weatherstrip, making sure to gently squeeze it fully closed all the way around the opening. It should grip snugly.
You might want to repeat all this for the rear passenger door, just in case. . .
