Testing AC vacuum lines.....
Ive had the "ac from all vents" issue for a while. I found that my vacuum line had popped of the back of the intake manifold. I fixed that, but it still isnt operating properly. Im having a hard time believing that happened and some other breakage happened at the same time.....
How can I test the lines to see if they are good? Can I hook up a vacuum pump to the input behind the intake and see if it holds pressure??

I'm going to fix mine here in about 20min, I'm going to do a write up on it as well, or try too. But like Lucky said, you need to remove the battery because you probably have broken/damaged lines in the harness.
