Leak from drivers side under dash?

I noticed the drivers side floor was wet yesterday as if something is leaking on it from the inside under the dash. Also, about the same time the break pedal started to make a small little squeak, I am assuming it is related b/c it sounds like it got wet and is now slightly cooroded or something. Has anybody had this happen, is it climate control related, a clogged exterior vent hole or something (however it has not rained in a long time here so, prob not it) TIA. 

First, tell us what the fluid is, water, coolant or brake fluid. If it is brake fluid stop driving it today till the issue is fixed.

get under your truck. In the well above the tranny, you will see 2 rubber ports. These are your condensate drains for your a/c, make sure they are clear.

The liquid had no odor or smell and it was not oily, so I will check the ac drains. Thanks.

EDIT: haha, no color or odor.

Have you been running your a/c in the last week or so? If not, has it rained lately?
