Wet passenger floor with AC running

[Retiredgunner]

98 GA, 3.1 V6. When I run the AC the passenger side floorboard is wet. It appears there is a lot of condensation dripping from some where. I have seen a thread going back sometime ago, about a drain line being plugged. Where is this drain line and where do I access it from, under the hood or under the car. Can somebody help? Thanks

Its on the pass side under the hood on the firewall.
It's probly clogged and allowing the condisation to drain into the car floor.
