Condensation line must be clogged. Water is dripping on carpeting passenger side interior. I just need to know where line is to try to unclog it.

Good morning,

The drain tube is under the accumulator. There is no specific picture I can find, but I attached a picture for you to view. I circled the area the tube should be located.

It has a 90 degree elbow that gets clogged with debris. Remove the hose, it just pulls off, and clean it out of all debris.
