Love your show! I have a 2007 Dodge Durango that I LOVE!
Recently,I was moving stuff around in the small cargo area behind the third seat and it was very musty. The smell that let’s you know there has been water sitting for awhile. I dried everything out and put everything back. I thought that something must have leaked from groceries.
But last week the water was back as the liner in the cargo bin was wet. Hmmmmmmm…not sure now. Could the water be coming up from the spare tire due to wet roads or could it be a leak from the rear window washer?
Have a real close look at the weather-stripping and the seal around the high center brake light.
If there is a (drain hole?) in the cargo floor pan, water could seep in when very wet out and you’ve been driving.
