Hey guys. Had p0449 a couple times early in the morning. I read up on the code here on the forums, but what's interesting to me is that I am getting a lot of water draining from under the Hummer. It looks like ac condensation, but it is a lot. Like a steady drip sometimes. This is my first summer with the Hummer, so I don't know if that is normal or could be something else tied to the evap code. My AC works extremely well, so maybe it is just condensation, but I'm always curious when 2 things start happening at the same time.

 

Turn off the AC, if the water stops dripping you know what it is. Or, get under and LOOK where it is leaking from.
