I've currently got 2 vacuum leaks . . . or atleast vacuum leak sounding noises. One is from under the dash on drivers side - I'm figuring that one is the brake booster as I had a similar issue on an Escape. (I already had the vacuum leak on the passenger side and fixed it by replacing the check valve last year).

The second vacuum sounding leak is from the rear of the vehicle. It sounds like it is coming from that vent on the drivers side just above the 'floor' of the cargo area. I don't know of any vacuum lines that would go that far back in the car and that is one thing that is confusing to me about this noise.

Does anyone have any experience with this noise or possible leak? Thanks for any help offered!
 






That vent in the rear is for the rear ac and heat. From my knowledge there are no vacuum lines that run back there. But what you could be hearing is the ac for the rear.
