Could also be fresh engine oil if you recently changed it. Keep in mind the oil filter is on the pass side also.

 

Ok so after a little more investigating the whole passenger floorboard is wet as well. It doesn't really have a smell. It does seam a little oily. And I haven't changed my oil recently. Also I don't use my A/C very often. The day I noticed it all I did was drive to get some food maybe a total of 2 miles and didn't use the A/C. I haven't noticed a difference in my brake pedal either, it still stops the same. And now after reading all I can think about is finding this nipple thing. LOL

 

Ohhh...............that sounds like a heater core matrix to me??
What with the whole of the passenger side floor wet and all.
Al.

 

I went to Dodge with a similar problem for my Nitro. My leak I noticed late and it was flooding my passenger side floorboard. Dodge informed me that I hade a heater core leak. I am now in the process of figuring out a way of changing it myself. I guess youtube here I come.
