So my Xterra has been sitting for a couple months in a rural environment.
(near identical designs as some years of Pathy)
past weekend I picked it up and drove it back to my new home state (Florida).
The drive was a bear but thats not important here.
I noticed this very unpleasant smell but figured it was from it sitting for a long time and maybe someone had used it ( my buddy had express permission to do so) and spilled something that never dried ( or so).
Also I thought the bad smell would be gone eventually because I had discovered a smelly package the day before and took it out....
however I also I noticed the air-conditioning was weak.
So I decided maybe the filters for the fans in the car are clogged also my eyes teared when I turned on the AC so I got even more suspicious.
Low and behold when I finally got to the interior filter I found a squirrel nest!
It smelled disgusting.
even after I took a while bunch out it still looked like this:
I took all out ( barely keeping myself from vomiting, I absolutely hate that smell) then cleaned the inside of the filter box with shop towels drenched in chlorox, then wiped clean, then some more cholorx let a chlorox drenched show towel sit in it while I ran the engine+HVAC fan.
Put in the new filters.
Sadly I still smell the squirrel nest smell when I put the HVAC on now.
Hopefully it will go away eventually, at least my eyes arent tearing up anymore.
