Oil under drivers side carpet

[Grimster]

I have a 2004 Yukon XL Denali & took out the mats to vaccuum noiticed that the carpet was wet & stained. I pulled the carpet back & noticed that the pad was soaked in what appeared to be oil. There is a 1/4" bluck tube that goes through a grommet that the floor. The grommet had a bunch of oil in it. I can't figure out where it's coming from, any ideas????

Drivers side, or passenger's side?
I wonder if it is a clogged and dirty drain to something like the moon roof or A/C?
Pics always help.

Could it possibly be coolant? Or is it definitely oil?

It's oil colored & has an odd stink to it. Someone suggeted that that line was for the rear A/C & that it might be oil from the compressor. It looks like the line might have a fitting right at the grommet.

not knowing where exactly your talking about really puts a damper on trying to figure out what your describing... pics would definitely help.

Do you have Hydroboost brakes? might be ps fluid from a bad seal in the hyrdoboost.
