I've dealt with mice getting under the hood on all of my vehicles. The Blazer is no different ... but, other than chewing away the sound deadening on the bottom of the hood, no damage....... until now.


Yesterday, when I turned on the AC, immediately mouse pee odor come out extremely strong!..........never before! The odor gradually disappeared after about 25 miles of AC operation (condensation most likely washed it out the drain.)


So, where did they get into my AC system? A quick visual under the hood didn't real anything. Is it possible they could chew in from the drain?


Thoughts?
