I'm guessing you might find Mr. Mouse's) skull and bones up between the sheet metal of the roof and the cab ceiling.. remove a sun visor and stick one of those borescope cameras through the sun visor swivel hole and fish around until you find him.. I think the mice can move up from the heater blower hamster wheel through the hollow front pillar to get into the space between the roof and ceiling sheet metal.. Lysol will help with hantavirus but don't rely on it (until they find a cure for the virtually certain death or at least permanent health effects of hantavirus)..
