I just got 2013 GS350 F Sport couple of months ago and started noticing wet carpet on passenger side. I have searched this forum to see if I can find the introductions on how to clean the evaporator drain or any pictures /videos no luck !!

Run the AC whilst idling, see if wster drips underneath the car. If it doesn't, your drain is blocked.
If it does, you could have a blocked sunroof drain...although I don't know whether that would result in a wet floor.

In my car, I had an issue with the rubber drain between the HVAC fan and the centre console. Water from the AC system in the centre would fill up in the fan and leak out. I just blocked the hole, the fan doesn't really need a drain.

Make sure the sunroof drain holes are not blocked. They are on either side in the front of the sunroof cavity. If they are blocked the water accumulates and spills over to the headliner when you drive.

It doesn’t drip when the car is parked and idles, I did notice water drips from the fan after taking the plastic off under the glove box. How do you unclog the ac drain??
Any pictures documentations/location of the drain?

thanks!

Maybe the this video might help... It's on a IS350 but some comments state it worked the same on their GS350...

You're killing me. That's exactly what's happening to me. I posted about it a year or two ago and didn't get anything. Champion effort!
To the OP, I have this issue but I do get water dripping under the car....if you don't it could be the drain. It's at the top of the tranny tunnel, give yourself 2 hours to get it out. But let the car idle, with ac on for 20 minutes
