95 olds88 AC water drain clogged

[johnbaron]

The air conditioner's condensed water (clear, clean) that should drain harmlessly out the drain and onto the ground is coming into the car through the passages that blow air onto the feet of the passengers.

Tried cleaning the drain pipe with a wire (it only goes in a few inches). Removed the plastic interior cover, but cannot see where to go next.

Have a dishpan catching as much as a quart of water on hot days within a few hours as it comes out of the places where air blows out onto the floor.

How can I solve this problem/ clear the drain line?

Maybe a little air pressure up the drain with a blowgun might knock the blockage loose. Not too much or it'll cause damage inside the box. Most of the time on GM's it's a spider web in the drain spout. The only other option I can think of is to pull the dash to get to it. Good luck

Thanks for the suggestion. I will cut the pressure down before I shoot the air up the drain. I will try it as soon as I get my car back from a friend in a few weeks.
