How do I stop my A/C from leaking inside from the firewall under the shroud? on 2000 Jeep Wrangler

Condensate drips from the drain under the hood, I've tried blowing air & routing-out with a soft bristle brush. I get tiny pieces of Styrofoam & filings from aluminum & plastic out? A/C is on when the leak occurs. Will I have to remove the black shroud that encases the evaporator? Then What if so?

it sounds like you drain is plugged but if its leaking inside I would try cleaning it out from the inside under the dash
Thanks, was afraid I would have to start there!
CLEAN CONDENSATION DRAIN HOSE OF DEBRIS
I worked for hours yesterday, blowing air & trying to clear drain tube with a small plastic bristle brush! Guess I move to tearing the shroud out from the inside. Thanks for your response.
