The drain tube on my 2005 Buick LaCrosse seems to be clogged. Where do I find the drain and how do I unclog it? Thanks.

First there are two drains. One is the A/C drain and the other is the drain for the area in front of the windscreen (where leaves and stuff can get in). Since I don't know your car, I can't give specific recommendations. 

Once you find the drain, you may use a little compressed air (don't over do it, or you may make a small problem into a mid size problem) or some string trimmer line, but take it easy as that also can cause damage if you are not careful.

```

Good Luck.

It usually protudes just in front of the firewall on the passenger side.
