Locating vacuum leak for cruise/ac issues?

Thanks for that info Chris, so I can look elsewhere for my ac issue then. My blower directs air whereever I select. From all reading been doing, I suspect its just a case of the system having low pressure, for I can jump start the compressor, just gonna save up for some manifold gauges and a vacuum pump and check the system out.
Must be coincidence that ac and the cruise are gone on fritz..?

I've detected vacuum leaks successfully using the spray parts cleaner method. Its amazing how just a small leak causes the engine to idle higher. You might try measuring the vacuum on the line to the cruise servo with a vacuum gauge on some kind of T-fitting with the line connected then disconnected and plugged. If there is a great difference there is probably an internal leak in the servo.
I have ordered many parts from rockauto.com and they usually have the lowest prices, most complete inventory, and they do ship internationally (from the US).
Also, the AC compressor will not usually engage if the refrigerant pressure s too low. There are low cost gauges sold that work like simple tire gauges. But if you add refrigerant, be careful not to add more than one can of the kind containing oil. I had too much oil in mine and the thing would cycle on and off constantly which is hard on the compressor clutch. Hope this helps.
