A/C drain clogged

[Nobby]

Running the A/C for 20-30, I notice the fan not blowing at all even setting the speed to high. I hear something blocking the duct work. I stopped for lunch and when I came back I notice water still pouring out from the A/C

Huge puddle, almost cover half the car.
Checked the fluid and confirm it was water.

Where is the drain and what can I do?

Little confused here....you say drain is plugged, yet you have condensate on the ground?

You run the A/C with no blower motor running?

Sorry about that, partially clogged A/C drain

Dead center on firewall- stand facing forward on passenger side- put left arm down in behind generator- and reach in to divot area- pull rubber elbow off- and trim the nipple so that the rubber flaps are gone!!! GM W-car are the only ones that use the rubber flaps on their drain tubes- and they are the only ones that tend to plug up-- go figure....they did it to reduce air flow out the drain so as not to waste cool air.....I do this to all W-cars..

Did exactly that, but had to remove the module since my hands are size of giants. Thanks for the info.

My next step will be to blow air into the plug from the firewall if this fails

I saw where the drain channel is under the passenger side inside the car. Wondering if I can drill a small hole and blow out from there and then tap the hole after. Seems like a lot of work though. Will wait and see

thanks again brcidd
