weird a/c problem

after a 2 hour trip today in humid 85* weather I noticed the a/c wasn't blowing out of the vents but the blower was running. got home and took the glove box off to see it the blender door was stuck. as I was standing there, on the passenger side, the truck started pouring out water from the evaporator under the hood. I know it's supposed to drip but this was a steady stream, and alot. as soon as that happened air started coming out of the vents. did it freeze up and block the air from going through?

That's what it sounds like to me. Could be low on freon or something is dirty.

Make sure your drip line isn't plugged up. Not enough airflow over evap will freeze it up or an irifice tube that's plugging up

I just recharged it after I put a new condenser in.

there was no hose. just a hole.

problem happened again today. took a look under when it started dripping. it's coming out of the seam at the front of the evaporator box, instead of the drain hole in the back near the firewall. I blew air to try and clean the drain but it seemed clear. also noticed the evaporator box doesn't have it's insulation anymore, would that effect it?

can I just drill a new hole up front and call it a day?
