The car is 13 years old now. Have you looked underneath it for signs of a
rotted floor pan? If it were just one foot area I'd suggest bad door seals,
but with such a widespread affected area I'd be more suspicious of a rotted
Does it smell like antifreeze? Could be your heater core is leaking.
Also noticeable if the windshield fogs up badly inside when you run
Aside from that, have a friend spray the car with a hose, while you're
in it ... paying special attention to the front wheelwells.

gm cars......moslty corsica/ grand am... had bad windshield seal.. leaked in
through the bottom.. pop your hood and make sure no leaves have clogged the
drain areas....forces water sometim es into the vent system. Spraying water
will do nothing.. unles you use a garden hose and soak the shit out of the
windshield and have someone in the car watching.. I've seen people buy dye
kits and soak the hell out of the car and use the glasses to check where the
source is.. good luck
Shall I assume it also rained?
Then it's obviously a leak.
You'll have to examine the body very carefully for leaks.
Twice I've had rain leaks with new cars.
Both times it was a body joint with a very small hole.
With such an old car it may be a rust hole or a poor window seal.
My 93 Old Achieva (same body as the Grand Am & Skylard) had the same
problem; after a mild rain there would be a lot of water on the passenger
There was a TSB, #431607 that addressed the problem. The bulletin had
instructions on installing a deflector around the air inlet for the
heater-A/C. I had the dealer do it; here's a link to someone who did it
bottom of the page.
Hope this helps.
