One of the most noticeable signs of potential rodent damage is if you try to start your car and you can’t get the engine to turn on. While this is an extreme sign, you can spot smaller clues by looking around your vehicle for rodent droppings, paw prints, scratch marks or teeth marks and the smell of urine. You can also pop the hood and look for exposed wires or scratch marks on the coated wires. Don’t forget to inspect the belts or check for nests under the hood. If you see exposed wires or fiber insulation, you might want to contact a mobile mechanic to do an inspection and repairs.
