Water in floor

If it was summertime, I'd say;

"a blocked A/C drain hose"

even in winter it may be; most (all?) cars run the A/C compressor when in "defrost" mode. Also could be blocked cowl drains, if applicable.

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 out floor.

Does it smell like antifreeze? Could be your heater core is leaking. Also noticeable if the windshield fogs up badly inside when you run your heater.

Aside from that, have a friend spray the car with a hose, while you're in it ... paying special attention to the front wheelwells.

Thanks guys, I forgot to mention that the water accumulated while car was sitting still so it wasn't coming from water splashing up from the ground. I will check out your suggestions.

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 side floor.

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 themselves:

Hope this helps.
