Passenger side ac leak in cabin

[08grey]

So took my first long trip in the Denali today. 700 miles in 85+ humid weather. Ac started leaking inside of cabin on passenger side. It was still noticeably draining on the outside when we stopped at the rest areas. Haven't had a chance to look at it at all just too tired.
Anyone experience this at all?

The drain might be slightly blocked. Try a coat hanger and see if you get any leaves or other crud out of it.

I have the same problem. I've hit the drain with compressed air and it seems to be better. Time will tell. Interested to see a better solution.
