No water dripping from ac

[ediekrager]

I never notice a pool of water under my 2015 S4 when the ac is running (like I have with previous cars). I even tried cleaning the evaporator with Klima Cleaner and no liquid drained out. I’m thinking the ac drain line is plugged, but I never have had any water overflowing into the floor area on the passenger side. How do I check the ac drain line to see if it’s plugged?
