'93 Vacuum diagram

Does anyone know where I can get a vacuum diagram for a 93 GA with the 2.3L engine. I'm trying to trace where the cruise control and vent control vacuum line go to/come from...I suppose I could rip the car apart and trace it by hand but it's hot out and it would be alot of work that could be avoided with a handy dandy vacuum diagram.

The reason I'm looking for this info is because my vent control stopped working mid-selection and my cruise control seems to be non-functional as well, I'm not really sure if they both went out at the same time but the hoses are original and it would seem like a broken line would be able to take both systems out in one shot. So if anyone has info or a diagram plz let me know.

It may have helped a tad, supposedly I know where the vacuum source is now...if I'm lucky it's messed up at the source

ok update, I believe the posted diagram link did help because went I looked at the throttle body the (what I think is) accessory vacuum hose is disconnected from it's hose end (the connector at the end of the hose) now it typically would be a breeze at this point except I can't see the disconnected hose anywhere in that area. Does anyone know which path it takes from the throttle body to where ever it goes next. Thanks for everyones help...I really gotta get me a factory service manual.

K, presuming you see th vacuum port, but don't see the hose itself that connects~~~~~~~

It slight possible the hose got lost somehow.

More likely, it came off. Start your path from the Cruise vacuum modulator motor, go towards the vac. port. If the hoses are at the modulator, they bound to lead to the vacuum source. Do some gentle pulling and looking, one hose [if I recall correctly] gets buried underneath a wire harness and is a bear to find visually from the top of the motor.

Look at this, and also look to left for some other component links of the cruise control, maybe this will at least narrow things down for ya.

ok an end to the madness, the problem has been solved. I found the lost hose, little did a know a few months ago when I was tightening my PS belt that this little hard plastic hose with a hard plastic wire slit wire loom around it was so important, back then I didn't know where it went so I tucked it up by the radiator. Well I found it again when I was tracing the hose through the fender towards the radiator but this time I knew what it was for. Plugged it back in and like magic the heater vents work and the cruise control works. Thanks for the help Knifeblade
