Soy based wiring IS the
Soy based wiring IS the problem. I have a 2003 Ford truck and a 2008 Mazda that are parked outside in my driveway as the rule all year long. I have found mouse droppings in both engine compartments. Aside from some insulation that has been a bit shredded (for nesting material) nothing else has been damaged. I have a 2019 Toyota Camry that is parked in the garage year round. Last week I could not park the Camry in the garage for a few days, so it stayed out in the driveway with the other 2 vehicle. Mysteriously the AC in the Camry stopped blowing cold air last week. An appt. at the dealership resulted in a diagnosis of "rodent chewed wires" and a repair cost of $8000 to replace the entire harness. I jokingly asked the service tech if Toyota was using cheese flavored wires and he said no, but they do use soy-based coating. This is absolutely caused by the enticing flavored wire insulation Toyota uses. For anyone to say otherwise shows a lack of ability to get to the truth.
