Anyone have previous experience fixing clogged AC drain in front left of cabin?

My RS6 seems to be dumping water condensation after long trips into the front and rear passenger footwell carpets did not realize it for a while because I run the rubber mats year round even down in Miami.

I'm getting water build up coming from the front dash area that soaks the front and rear passenger footwell carpets.

Has anyone else had this problem and solved it? Thinking it's simply a clogged drain that is supposed to run onto the ground but instead is backing up into cabin due to being clogged. Insight and experience appreciated...
