The easiest thing to do is to take all the carpet and underlay out and wash it all with a wet/dry cleaner...
You may still have small puddles of stale water sat in the floor tray. that, combined with the wet carpet/underlay is the cause.
It's not too difficult to take all the carpets out. It's just a bit time consuming.
Once out, clean it as you like really...then allow to dry completely before replacing and make sure the interior floor is dry too.
Obviously, fresh air will help so open all the windows/doors whilst you do the work..
It's not hard and will give you an idea as to how all these professional car cleaners do their jobs...
hope this helps.
