You don't state under what conditions the water appears but if this happens only when you wash the car or after driving in the rain the following might be helpful:
"Some customers may state that there is water leaking on the drivers floor. The condition is noticed when driving in the rain or going through a car wash.
Recommendation/Instructions: If normal diagnosis is followed and a site of the leak cannot be determined, check that the windshield wiper harness grommet is fully seated into the body."
You might check along the bottom of the windshield to make sure any drain or 'weep holes' aren't plugged-up. With some vehicles water on the passenger side floor is indicative of a faulty heater core. It could be related to the HVAC system. Good luck!

I removed the passenger carpet to dry. I was in a real hard rain, before I discovered the water. The carpet was reinstalled. I was on another trip, got into more rain, this time only the mat under the carpet was wet. I don't see any water on the fuse panel.
Thank for your suggestion,

On my C5, I had the windshield replaced and a year later found a whole lake of water behind the passenger seat, after driving in heavy rain. Front carpet was wet but no standing water.
Turned out the W/S was leaking, water ran along the trim inside the door sill back to behind the seat. When that area got full, it overflowed back forward again.
These things can be tough to find, let us know what you discover.

This will sound a bit cheesy, but it worked to solve a very difficult to find water leak that the dealer could not find after multiple attempts. Since the puddle was in the front footwell they were focusing on the front half of the vehicle. As it turned out the water was entering from the rear. Water travels significant distance with the help of gravity, acceleration and the capillary effect of most materials. Lack of seam sealer was my problem.
With the interior trim removed, tape toilet paper in non-continuous sections throughout the interior on the vertical surfaces. Toilet paper dissolves fairly easily when water hits it, so it provides evidence where the water entered. The paper has to be placed non-continuous (not touching each other) so it doesn’t wick from one sheet to the other, thus ruining the evidence trail. I’m certain other types of paper will work if you have something against cheap toilet paper. Yes, I was embarrassed by the appearance, but it worked.
Good luck.
