AC compressor is not getting voltage

On my 97 9000CS the air conditioning just stopped suddenly (on a rainy day).
I have checked the wire at the compressor, and that has no voltage at all. All of the fuses are OK.
I dismounted the AC relay (near the battery) now it is clean and tested, works fine, but I still don't have AC. Relay has no signal to act.
Questions:
- Is there any other relay to check? (I saw in previous posts that there is one at the glovebox, but I can't see it on the wiring diagram).
- How can I check the AC system charge easily? (Is it possible, that system stops because of missing freon?)
- Can I connect 12V to compressor directly? What happens?
- Which sensor could tell to the AC control not to turn on the compressor? If any, please tell me what that sensor does (I am more an electrical person than mechanic) and what I should measure on it.
