The AC relay is located in the under hood fuse box. The cover should have a legend for location. Its one of the bigger black ones. You can rotate it with the horn or ABS one to see if its the problem. You may have a small fuse also in that box for it. If this doesn't solve the problem then you either have a leak or a computer problem. What a shop will do is try with a bidirectional data scanner turn the AC on.
