I have a friend who has a '96 contour duratec, 5-speed. The engine has been replaced with a '98 model and after the swap neither the cruise or lower air vents will work. Sounds like a vacuum leak to me but I was wondering if anyone may know what I should look for first. He's finally bringing it to the shop where I just started working and it'll prolly be my project so I want to get it done quick if possible so he isn't charged alot. I'm only slightly familiar with contours so any help is greatly appreciated!
