1999 Mountaineer, 83K miles, no garage so it sits outside. Pulled the center console to replace the pre-cat O2 sensors. I cut the carpet back to access the service panel and when I pulled the carpet back, the driver's side front carpet padding was soaking wet. Seems to be water, not anti-freeze. Are there common areas for leaks to occur that would get the carpet padding wet? The carpet itself feels dry. Thanks.
