What color is the goo?
I haven't had any come through my carpeting, but, one day while digging under the dash, I decided to take apart an electrical connector, and found it covered in a sticky goo. It had the consistency of thick honey, and was close to yellow oxide in color.
Goo, will eventually work its way down from wherever it is coming from. What I mean, is it could be coming from someplace higher up, and it just took several years to work its way down.
