After my truck sat in the garage all weekend without being driven (I was painting the wheels), I got in it on Tuesday and when I turned on the fan to run the defroster, the blower motor sounded really rough shot a bunch of insulation and shit out of the vents. Well when I got home I took the motor out to find this:
A huge ass mouse nest taking up over half of the fan.
And those bastards used the insulation from under my hood!
Didn't see the mice, guess I gotta find a way to kill all the mice in the garage..
