Why does it sound like there is someone on a respirator in the back seat of my ford?

Hello, I would suggest having a technician near you to have a look at the concern and hear the noise you are hearing. That's really the only suggestion I have. There's no way I can know what "someone on a respirator" sounds like to you, and I need more information as to when you hear this noise, the frequency of the noise, and more questions.
