Yep, you got it. A nest on top of the filter, at least one of them was still alive.
I've about had it with mice.

I have an '18 2500 but I posted in here because of the higher traffic and thinking the AC systems are pretty similar.
I've noticed the smell the last day or two, 100% worse when the AC is on. There are mice around my barn so I figured one crawled in somewhere and died. I have opened the glove box trying to look where the cabin air filter is and I can't smell anything coming from that area.
Anywhere specific I should look?
Gas engine.... 18.2mpg, 17.7mpg, 15.2mpg for 400 mi.
The 18.2 and 17.7 were set at the same trip, descending from the highest point in Ohio. Couldn't believe when I saw that number on this truck.
The 15.2 was not set on a highway road trip, it was putting back and forth to work on rural roads. Not surprisingly, the 80mph interstate driving trips don't give as good of mileage as my 50-55mph commute.
That extra "1" is there on the gas trucks too. I haven't seen an explanation for it.
It could be something useful like a gear indicator, but apparently it's more important to just show a 1 all the time.
I have an '18 2500 gasser and the newest Haynes manual is for 2015-2016 2500 as well as 14-16 1500.
Is there a better manual available specifically for the 2500?
