Wet passenger side carpet

2014 toyota tacoma access cab. I've got air conditioning condensate dripping out of a hole under the passenger side of the Hvac box. I've made sure the drain is open and it passes quite a bit of water when the Ac is running. The leak only seems to be an issue when the blower is on high. Any ideas on where this hole leads to?

 

I think I've found an answer to my AC issue. I was reading jp316's post about his AC & he had a picture showing the hole in question plugged. Go figure. Thanks all and thanks jp316 too!

 

Thanks for updating your thread. Hope it all works out for you. No one likes soggy carpet.

 

A stinky, soggy carpet...

 

@Radar787 , how did you fix this issue?
