1) I washed my car thursday at a trusted andf tried auto/manual carwash.
2) I did over 300 miles of Highway driving between thursday and tonight.
3) Last night a female passenger spilled coffee w/ soymilk in it around the passenger carpet, seat, and the cupholder area. I cleaned it out and did not notice any stains on carpet or footwell area at the time. Last night it also started raining really hard...after midnight all thru the night until around noon today.
4) I drove thru the pouring rain to the local mall this morning w/ a male passenger and he had an yellow and brown umbrella around the footwell area. He had no drinks nor did I have any drinks or food in the car.
5)Tonight I noticed my glovebox light was NOT working. Then a minute later I noticed these stains...on both sides of the car.
6)I checked my coolant and washerfluids (the only blue-green liquids in my car that i know of) for any leaks or anywhere it could get from the engine bay into that area. After searching I could not find any spills or leakage. My coolant and washer fluid was alittle lower than I'd expect them to be. Also today whiles driving in the rain I may have sprayed my washer fluid to clean my window...which is normal for me when it rains..but I don't recall doing that today at all.
Okay, The million dollar question, what is this liquid?
It had a , slight mildew like odor to it (but that could have been the carpet that was still damp from the rain water from my friend's shoes) and it was already dried into the carpet when I saw it tonight...I did not recall seeing it earlier today...and it's something I would have definately noticed. Also when you peel back the black footwell area-upper-shield the liquid does not appear to be dribbling from behind the shield because there are no stains on the carpet there. but more likely it is coming out of the vents or another opening on the black shield.
