The Volvo site just shows as being out of stock, rather than unavailable. I'd send em an email or give em a call to see when they'll get some more. In the meantime, I have the wiring diagrams for a 1991 744 non-turbo, which is very similar to your car. It'll get you started in the right direction, anyway.

One thing I would check first is to make sure nobody has fooled with the wiring, like Chris said. On my car, some mechanic decided it would be cheaper to BYPASS all the A/C safety stuff with a Radio Shack switch hooked DIRECTLY to the compressor. I talked to a Volvo guy here and he said that wasn't that uncommon! Anyways, check the relay tray for any extra relays. A listing of them should be in the FAQ; if not, I'll email you a list.
