CV-713 air conditioner drain

anyone know where the AC drain is on the Granite? mine is starting to overflow on the floor, so i am thinking the drain is plugged up.

Open the hood and look on the firewall almost in the center on the bottom you will see a black hose coming out with a 90 degree to drain downward. I taped a knife to a stick and just cut it off. They say dirt can get in there with it cut but I didnt care, I wanted to drain it. You can also rigg up an air line with a piece of copper tubing and shoot air up it to clean it out.

thanks. the truck sat for over a year before we got it, and i think a wasp made a nest in the drain tube.

Just had same problem in a Vision we have, had to remove both A/C and heater core and clean it all out, not fun but everything works great now, we tried poking things up the drain tube, blowing air up the tube, nothing worked for more than a day or two, take it apart, you will be amazed at the crap you'll find.

Rather than blowing air, putting a shop vac on the drain would be better.

the ultimate way is to take the dash apart and pull the cabin filter out and they make a spray for ac condensors that you spray on the fins and let it sit then wash it out with a hose...someone told me wal mart sells it in the ac section.
