I saw a post in 80/100s about leaks and wondered if anybody had the same thing in their truck? My 90 extra cab had a constant wet pass rear floor. Could never find the leak. Figured it was the rear window. Now, my 2000 Taco has the same frickin leak. Cept it's on the pass front. Pick up the mat after it rains and the floors soaked. Startin to smell like a wet dog!! I heard it could be from the fresh air vent being open when it rains?? Could that do it, or should I check something else? It's goin into the dealer next month for some other stuff, don't know how much they'll bone me to find the leak.
