Truck leakin in rain water???

[Ford Cowboy]

Have a 2000 f350. When I got in the truck this morning to head off to work, I noticed that the floor liner was FULL to the brim with rain water. I didn't have a whole lot of time to look around, but I noticed that there were water droplets up under the dash. It's leaked for a while now but never ever this much. I always thought that it was leaking through the drivers side door, but now I am thinking its comin down under the dash somewhere?? Anybody had this problem? Thanks for any help.

It's not at all uncommon for the Windshield to leak in the corners. Be sure it's not filling the GEM Module and causing trouble there.

You should be able to look up behind the dash with a good, strong flashlight to see whaere it's coming from. I've "poofed" talc sometimes to find a leak
