Air conditioner blowing from defrost vent

[tonydiv]

I'm having a terrible time finding the vac leak. I'm thinking that perhaps the line is kinked somewhere in the dash. Any ideas?

has anyone gotten any further with this problem.....my expo will blow from the vents for a while.....and then switch to the defroster vents...and then i cant get it to switch back...which is terribly annoying in south florida...pictures or commentary would be great!!!!

I have a similar problem. My 2004 NBX blows strong from the dash vents....but under heavy acceleration they cut out and it switches to the defrost vents.....is this the same problem the vacuum line?? any help would be greatly appreciated.....thanks!!!

Thanks and fixed by help here

The vacuum line in question actually comes out of the electrical center just left of the battery. ( haynes book says starter relay but i dont really know).

The vacuum line comes out of the box and goes right by the bottom, left, rear corner of the batt. Thats right where mine was broken. Slipped a piece of hose over the broke section. Success!

Thanks again everyone.
