I notice a small puddle of liquid on the garage floor so I checked under the rdx....there was like a hose right above where the liquid is.

anyone know what this is and what these liquids are coming out of it??

i have some pics here...see where my finger points to

thanks alot

 

looks like a drain, or a vent hose. for what, I dont have a clue.

 

Its probably the AC drain. The puddle is a clear odor-less liquid? If so its water from the AC.

Ok, I have a question... Why does the ac drain hose sometimes drain water and other times doesn't? I lightly used the ac today and noticed a puddle under my car and saw that hose too, but how come on other days when I used the ac more, it didn't drain/leak water?

 

Hot, humid air condenses water on the cold evaporator under the dashboard (like iced-tea out on the porch). The water then runs out the undercar drain.

More humid; more water.

 

Free undercar facials!!

 

I have noticed today that my Acura had lots of water leaking , so i checked and traced where exactly is leaking and find out it's coming from the AC drain hose.
I did not notice that before but i anticipated that from humidity .Thanks for sharing
