Before I start, I just want to say thanks to everyone for the all the help reading this forum has given me.
I have been fighting a driver side wet floor board issue in my 2000 GTZ for more than a year. I never noticed any wetness during the dry hot part of the summer while the air conditioning is being used all the time. But during the rainy part of the year, I could have as much as an inch of water. From this I drew the conclusion; the problem was not with the ac evaporator drain. As part of the diagnosis, I noticed some wetness on the left side of the car, just in front of the drivers door. I had put a battery wire for the amps in the trunk that entered the inside of the car near that location, so I thought I had not sealed it up very well. I removed the fender and used some Rust-oleum LeakSeal, an aerosol rubber sealer. It really makes a mess but does a good job sealing things. But that did not fix the problem. I decided to take the fender off again and noticed the drain for the sun roof was not installed correctly.

Easy enough to fix.

The wetness on the right side was fixed, but there was still more water coming in. To search where the rest of the water was coming in, I removed the carpet. I am going to replace it anyway. That is when I found the leak at the ac evaporator drain. I am sure there are some decent pictures someplace in this forum for this type of fix, but here is the ones I took. Hope they help.

It is a lot further down on the firewall than I thought it would be. Whoever said this is a PITA to work on was not wrong. I tried to use some 3M Windo Weld. But I found it stuck to my hands better than it stuck to the car. Every time I removed my hand, the weld came with it. I decided to switch to some silicone sealer. While smearing this sealer, you cannot see where it is going as you hand is in the way. I put as much as I could trying to make sure I got everything covered.

I used a coat hanger with about a half inch on the end bent at 90 degrees to clean any of the silicone that went into the drain. I hope this now fixes my problem. If I can get the can close enough, I will also spray on some of the Rust-oleum sealer.
I will try a car wash soon to see in any water comes in and report the results.
