This thermostat is for ls4, if that isn't what you have, let us know. in the picture, 305 is the thermostat. I realize the text is a little small, hope you can read it.
Wiring, schematic, electrical diagrams, fuse diag, error codes, torque settings etc are basic contents of these online books they have here on this website www.reliable-store.com I have attached.
Must check it out

Need clarification...
Does the compressor run steady, cycle on and off continually or even come on at all? If cycles on-off then attach charge manifold/gauge set and bring freon up to proper level. If does not come on at all, then start engine, turn a/c on, remove two-wire plug from low pressure cut-out switch mounted on accumulator. Jumper the wires at plug and see if compressor comes on. If so, bring freon up to proper level.
If charge level was low then check for system leak after system charge with an electronic leak detector if available.
If compressor runs but doesn't cool vehicle then with engine running and a/c on feel (carefully) the lines. High side line should be hot (be careful) and low side line should be cold. If these are both true then it's possible non-cooling condition is due to air temp diverter door not operating or heater valve not shutting off (if so equipped). If low side not cold it could be a plugged orifice tube. If high side not hot it could be bad rings on compressor. Both conditions can be diagnosed with a/c manifold gauge set by noting the pressures.
For safety... if not familiar with differences between hi and low side components or with charge equipment then please take vehicle to qualified person for service.
