My parents have a 99 Grand Caravan, and a mouse made a nest in the engine compartment, inside under the windshield/wipers theres the vents, and theres a fiberboard type panel. Hard to describe, but the panel sagged, and the mouse got in and filled it with bedding and piss. I vacummed as much as I could, and blew the rest with an airhose. The panel stills sags a little, and my dad sprayed bleach, febreeze, dryer sheets, and it still smells when you have the vent on. I don't see how you could get to it, short of pulling the engine. Could this be accessed under the dash? My parents are retired on a fixed income/social security, and I need to find a solution other than paying a shop $500 to pull it.
