Drivers side floorboard water leak

[Juddys123]

I have a 1990 short bed 5 speed 2.3. For the entire time I’ve had the truck it’s had a bad water leak that puddles up in the drivers floor pan. I’ve included a picture below. I think it’s a bad windshield seal but I’m not certain. Any advice helps. I have cleaned out the leaves from the the drain in front of the cab but this didn’t change anything.

It could be the drip rail on the corner of windshield. My bronco ii had same issue but on passenger side.I couldn't see it leak in until I took off trim on the inside l. I ran a hose all over windshield and drip rail areas until I found it. I suggest placing a hose on the cab with end facing windshield turn it on and let in run. If it leaks bad enough you ll see where it's coming in. I did this on my bronco ii to fix like 6 waters leaks and found every one with this method . Hope this helps
