The most common source of water on the floor is a plugged a/c evaporator case drain hose. This drain is generally located down low on the engine side of the firewall at the passenger side and is usually a small short open ended hose that points down. Debris and bugs will clog this hose which makes the water that condenses on the evaporator [whenever the a/c is on] overflow and leak out of the heater/air conditioning housing and onto the floor. If it hasn't rained for some time yet you are still getting water on the floor I would bet on this hose being plugged. A puff of compressed air is enough to clean most of them out. Most sunroofs have one or two small drain holes that allow water to run down through the door pillars and onto the ground. If you pour a small amount of water around the top edges of the sunroof when it is closed you should soon see water dripping onto the ground under the outer edge of the vehicle. A few sunroofs just rely on tight weather stripping to keep the water out but those usually drip water on the driver or passenger if they are leaking. I see a lot of leaky windshields but again, it has to be raining for water to get on the floor from them.

Try the solution at this link. It includes steps and pictures to guide you. I had this problem with an 06 Vue. The right way to unclog the sunroof drains Saturn Spot Good luck, it took the dealership 4 or 5 tries to get it right. Fortunately it was under warranty and there were still Saturn dealerships at the time.

Thanks for the info on the sunroof drains. I'll check that out. As for the A/C, I rarely it, maybe couple times per summer. I should have been more specific, the water only collects on the floor boards after a good amount of rain, full day or more, and I haven't found any moist/wet areas on seats, dash, doors or anywhere other that on the floor boards. That's kind of why I'm suspecting it to be the windshield, but wanted to make sure before I had it reset, resealed.
