...noticed an odor creeping up inside the ole '10 Pilot & I searched under seats, expecting to find some spoiled "groceries" that had maybe rolled there unseen...but, didn't find anything. After some thought, and even though I'd changed the cabin air filter just a few months ago, I decided to look at that and install a new one while at it. Behold!! A heckava mouse nest right on top of the filter...and a dead mouse! With a pretty strong shop vac and some work I'm thinking that I got all of "it" out and a new filter installed (...cleaned the filter bracket with bleach, BTW). The Pilot is garaged (enclosed) every night, incidentally, and most days & no signs of mice. In any event, odor now gone, fortunately. Now, in looking around as best I can I just don't see an air intake that a mouse would see as a "door", 'though I realize they require only a <1/2 inch or so for entry. Am I correct that the HVAC intake is the black plastic "plenum" at base of windshield/rear of hood? ...and, except for the "screen like" area on top and the two removable strut top access panels, there just aren't any "holes"? Yep, I'm wondering how in the heck did that mouse get in?
