Question Where is the water coming from?

The vehicle is a "91" Pontiac Grand AM, 4 cyl, 2 dr. There is water forming puddles on the floor of the passenger side of the car, it doesn't have to rain for it to accumulate, but when it rains there seems to be more. All other fluids have been ruled out, it is water. No visible leaks can be found above the floor, ruling out the windshield, dashboard, windows, and doors, all are dry, seats and under the seat are also dry. It is just the floor front & rear where the water accumulates. The car also doesn't have to be driven for it to happen, ruling out being thrown up by the tires underneath. Any suggestions of where to look, or what may be causing this to happen would be greatly appreciated.

If it is truely water, if car has A/C, possible drain hole for condensate drain is plugged up.

Check the evaporator drain under the hood on the firewall down low/passenger side.See if it's clogged.

If the A/C drain checks out, have a look at Alldata.com as there have been numerous bulletins on water leaks on this era Grand Am.

See any GM dealer for a full copy.
