2007 E350 Mouse Smell in Heater
When I turned on the heater this morning there is the distinct mouse deposit smell. It is fine when the blend is on cold so AC is not affected It comes in when blend is on heat. I am assumung the droppings are in the heter core box or the ducting before the blend door. I am not familiar (yet) with the ducting system.. looking for advice on where to start looking in some sort of logical manner Thanks
