Moisture Odor- F-150 Platinum
 

Looking for some advise.....I'm the original owner and have had this issue with strong moisture odor coming from the inside of the cabin. It happens only when it rains or snow melting. Have looked everywhere for wet spots on interior roof , carpeting under seats etc....Have opened the roof top and inspected thoroughly and have found no areas of puddles or standing water with the inside rails......Any suggestions or has anyone have this issue ???

You might have to peel up the carpeting to examine under the carpeting and look for rust developing on the floorboard.. There's a chance there could be an issue with the drain for the heat/ac box.

I agree, if there was constant odor, but only happens when it rains ...Thats why Im thinking there has o be some drain plugs or leaks I'm not seeing ..........
