Default HELP! AC condensation leaking from under dash!

As title says, after my AC has been on for more than 5 mintues (2001 SS)..........if I take a corner with any kind of spirit I get an ice cold splash of pure water on my feet. SO etimes it seems it is more than a few ounces that come cascading down. As good as this feels in the Fresno, CA heat (lol), I would love to fix it. I imagine some kind of EVAP hose has came loose. Right? Wrong?

My question is: Has anyone done this? Any tips? I will do anything possible to not remove the dash as it is a PITA.

Please help. Thanks!

There is a drain line off the evap box and its become plugged with snot (dust+water). Run a coat hanger up the line, and your problem will go away.

Is it possible to get to without removing the dash?

Hmmmm. It still does funny things when I start the car......without the AC on. I get a bunch of huminity fogging up the windsheild in the center......near the dash vent. Weird. Espicially since I live in the 90*+ Fresno heat.

More noticeable at night? Is the switch on vent? Inside windshield dirty?

Maybe. No. Kinda.


It does it in both day and night, more at night I guess. Usually the following stratup after I ran the AC pretty hard. The switch is always at off when I start my car. The window isn't 100%clean, but not dirty by anymeans.
