I honestly see this everyday at the dealership. They really enjoy slipping in the HVAC (duct work) and are prominently found in blower motors and within the dash area.

Living in Vermont, I have a lot of clients that find mouse nests in their automobiles. One of their favorite places to nest and chew is the air filter. This is really bad for the vehicle, because if a seed or dirt gets sucked up into the engine it could cause major damage.
We have found the best way to evict the mice is to always have mouse traps under the car in the garage or driveway. Whether you use "have-a-heart" traps or the old spring versions is your choice. You may find you catch a whole bunch in a row, and then your traps stay empty for a while. Don
