If it pools up in there with the A/C on, then it's a clogged evaporator drain
(rubber hose on the RH front of the car that drains the evaporator. It's
clogged with debris, clear it out with a wire.
If it leaks only when it rains, it's a seal or windshield/body seam leak.
Dealer's problem, 2002 vehicle, covered by the OEM factory warranty.
