I was vacuuming my truck this morning. And when I lifted the passenger side floor mat the carpet had about a foot in dia. spot of mold, Still fuzzy mold so it's still alive. I can't find any signs of a leak by the Ac drain line or the heater core under the dash. And it doesn't smell like antifreeze. I am gonna take it to the dealer and have them mess with it. What do ya think I should do? Demand a new carpet or just let them clean it. Now that I uncovered it, it really smells. Also Do ya think this will be covered under the extended warranty. Any ideas.
