How do I find all the Vacuum Lines?

Have the problem where the air is only coming out of the defrost vents. After searching around it appears to be the vacuum lines that have a leak. The problem I am having is finding exactly where the lines are in the car so I can check them. Could anyone help me find them? Thanks a lot

Im in the same boat except my a/c&heat work fine, but my cruise control dosen;t any someone told me I could still have a vacume leak. The best thing I could come up with is just take the time and check every vacume line you can find.

P.S. its not a car its a Jeep

Most of those lines run from the back side of the engine, along the firewall to the passenger side fender, up to the front of the fender, under the battery box.
It's common for ppl to find their vac leaks under the battery box...

I have taken my battery and battery tray out and found a vacume line completly seperated repaired it and looked at everything I could find and no more leaks. Like stated above I guess I will check the obvious spots around the intake tomorrow between shifts
