My son and I were in a parade Friday afternoon with my Duece and a half Army truck and it was cool out so we had the heat on the whole ride to the parade, during and after. All of the sudden my son says, what the heck! a newborn mouse came out of the defroster vent. I could see another one in the vent. I wondered where the mother was, well the next day we took off the defroster hoses and found a big nest and four more dead babies, still no mother. Then my son disconnected the defroster hose under the steering wheel and lo and behold a very big dead momma mouse, dead of course. It was starting to stink pretty bad in there until we got rid of the whole bunch of them.
