I have been going crazy trying to find the elusive vacuum leak for my A/C vents. Its been defaulting to the defroster for 2 weeks since I installed the new fan motor. Thanks to everyone for your assistance and advice. The cruise control failed years ago so I disconnected the cable. It kept accelerating until we hit 90 mph. Thank God I was driving and not my wife or sons Any correlation?
Is there anyway to bypass the system so it only comes out the dash vents? Don't need heat on my feet or a defroster. I need A/C since its been hovering around mid 90's here in South Florida. I did find a capped unused port on the manifold yesterday. Thanks again for any assistance.

If it just the vents that are not working. It's most likley a vacuum leak.. Can't tell you where to look as it could be any vac motor, hose or connection in the system.

It is a vacuum leak. Someone said it could be the canister under the front bumper? He was recommending a by pass. Hmmmm? What do you think?
