leak rear passenger side on 2002 Chevrolet Trailblazer

Leaking water is coming out of rear passenger side...I noticed it is coming out of a rubberized nozzel that has a chiseled end. any ideas?

Does your Trailblazer have rear A/C? If so your seeing the water out of the evaporator drain.
Yes I do have a rear a/c unit. So that would be the rear drain, which now makes total sense! Thanks for the answer!

if your trailblazer has a sunroof this could be the sunroof drain hose
No sunroof
