Run the car parked for 10-20 min with the AC on HIGH in the fresh air (NON RECIRC) mode. If there is any humidity in the air, the evaporator will remove it and you should see water dripping out of that tube on the fire wall.
Seeing water on the ground under the drivers side is a good thing!
If you DONT see water, you will eventually have a leak on the inside in the passengers foot well.

There are other drains that can cause water in the car issues. The windshiels cowl (area below the windshield) is the fresh out side air intake for the HVAC System If that area isnt draining, it can fill up and dump water into the HVAC System.
If I were you I would remove the windshield COWL cover and see if that COWL drain trough is properly draining correctly.
If you run water on the windshield, there should NOT be any build up of water in that trough. It should all just drain out.
Here are some pictures of the intake portion of the HVAC ducts and those drains:
UDDER Drains on the drivers side:
Passengers side COWL DRAIN (behind the battery shown disconnected from the cowl)
Pic of the drain tube removed:
NOTE!!! Do not remove the tube to flush it. Just disconnect it from the cowl and use a garden hose to flush it out. Its a pain in the sack to get it back in correctly!

I believe I am having the AC problem, at first I believed the leak was coming in the door sill, which it was... I fixed that little problem with some sealant. The problem is still there... I just drove from NC to GA for christmas there was a very little bit of rain that i drove through... not enough to flood my floor boards however I ran my AC the entire time, I have pulled off the pannels under the blower motor and they were SOAKED! it looks like the water is pouring out of the blower motor its self... or somewhere in that area
I cranked up the AC and looked for it to be leaking on the inside... or outside of the vehicle I saw neither, however there is alot of condensation where the drip spout is supposed to be, what should I do!??

No,,,,I doubt it. The little black rubber 90 deg fitting is clogged. It causes the condensate to build up inside the HVAC air box and run out of the fan area! Seen this problem on 50 different cars! Very very common.
The fitting is on the fire wall.

i pulled the AC tube off no clog, along with the cowl runn off tube and no clog, what else might it be?
i took a tube of sealant and ran it where the cowl and firewall meet hopefully that will work, not looking forward to trying it out though... the water rains down over my ECU and the rest of my electronics there...

There is a lot of good write ups on the Coupes and Targas, but nothing mentioned about Vert leaks. I have a 02 model that will leak from the top of the lt & rt door glasses in various sports 
. Has anyone done a write up on Verts?

I'm printing this thread in the AM. I was able to clean up two of the three udders on the drivers side by hand. There wasn't much there, but it's better than nothing.
I didn't notice the third one. Can I get to the far right udder without removing the wheel and panel?

There should be THREE but one udder could be missing. They pop in and out pretty easy.
I have big hands and arms and I can get to the third one but its a chore!
Hire a kid with samll hands to check to reach in there. They work cheap.

Bill, resident leak expert or anyone else who may be able to help. I have owned my '02 M.Y. Z for 3 years now and just in the past year began getting water leaks on both Driver's Side and Pass. Side windows (A-Pillars) which then leaks down to the door sill and onto the carpet.
I have posted this problem before on most of the forums and have had a few responses leaning towards a windshield replacement as the culprit. However, I have never changed the windshield in the 3 years that I have owned her. If the previous owner did so, then it held tight without leaking for the first 2 years with me.
Below are pics. of exactly where I have seen the water dripping immediately after a down-poor of rain.
Any insight is appreciated ! Again this is on BOTH DRIVERS AND PASS SIDE.
Water drips right out of here where my index finger is from the bottom of this A-Pillar Rubber seal. There is a little tab that holds the rubber weatherstrip down where the water actually drips from. I'm guessing the seal is shot underneath ?
Water comes drips out of this little tab holds this weatherstrip down.
Then water drips down here to door sill and onto carpet.
If the culprit is a replacement windshield would the water be leaking from these areas ??

Badass, your timing is creepy. I have been dealing with a leak that I could not indentify. I saw your post yesterday night after I got home and had a revelation.
My driver’s seat carpet (below your butt) has been getting moist. I also have noticed moisture on the passenger side carpet that goes up to the doorsill.
It was not until our heavy rains stopped yesterday that I decided to take the Z for a drive. I drove to Burger King and went through the drive through. I paid the dude and waited. I cranked up the heat to max and hit the front defrost button.
Something from the corner of my eye caught something: a small amount of water dribbled down the plastic down to the carpet on the passenger side. I have marked it in the photo. You can see the “trail” of water left behind.
When I set the vents back to me, the little dribble stopped. I went back to front defrost and the dribble came back. This leads me to beleive the air in the a-pillar vent is pushing water down the path.
Using the A/C has never given me water in the passengers foot-well. I checked all the udders and the A/C drip under the car. All clear.
I am pretty sure this is the a-pillar leak, but anybody’s feedback is appreciated it.
