What is this hose, AC hose? It appears to be dripping a little bit of water when AC is on but stops shortly after AC is off?

P.S. ...btw, my AC was installed last Tuesday but lately, it has lost it's cold/cooling air so I will have to see what's up. Other than testing the dye/crack...maybe it's connected to this hose too?

 

You answered you own question, now fix your leaking AC drain hose.

 

Its supposed to go through a hole in the floor and drain under the car. Sometimes it pops out of place and drains into the car.

 

Heh, thanks for the heads up you two.
