Interior drain plug

I was wondering the same thing honestly. I'm still going to check the ac drain, it only seems to happen when it's raining. It's never happened while driving on a dry day with just the AC on.

I hate to bring this back from the dead but I'm still having some issues. I've confirmed it's not the AC drain plug, and the grommet in the fire wall has been fixed. I'm still having a lot of water that appears to be getting in from under the vehicle because I can't see where water has dropped down, it's just a puddle of water. Any other recommendations are greatly appreciated, I just finished my fall semester so I'll have a lot more time to work on the Z and hopefully get this handled without sending it to the dealership.

Edit- this morning after a hard rain/snow it was the worst I've ever seen it. Nearly 1.5- 2 gallons of water under my seat. It has to be coming from somewhere along the windshield or firewall.

Edit #2 found another grommet in the fire wall that was popped out. ( I'm the third owner of the z). This fixed my issue. It's pretty crazy I didn't think that much water could be coming from the firewall, but when I turned my heat on to defrost my front windshield, all that water perfectly streamed down past the popped out grommet and into the car. If anyone has this issue and have had audio work done in the past, the first place I would check is the firewall. Thanks for the help !
