If you check the power to the compressor clutch & find 12 volts, the clutch is defective & will need repaired/replaced. My Gisele is, however, that there is no power. Could be a bad switch, relay, connection, etc, OR, low on refrigerant. Most systems have a low pressure cutout switch to protect the compressor in case of refrigerant loss. You will need a refrigeration gauge set & the proper hose fittings to determine this. Perhaps you can find a local HVAC guy that will be willing to help out. I did them for years! If the refrigerant charge is indeed low, refilling it will get it up & running, but you will need to find the leak & repair it ( it disappears only by leaking out). This can be found with electronic detectors, or even soap bubbles. Repair will depend on the cause. Sometimes, the shaft seal on the compressor will leak from long periods of inactivity, and will often re-seal upon usage. (The seal is actually accomplished by a very thin film of oil on the seal surfaces, which can drain off during idle periods). If the system is empty, and has been for a while, after repairing the leak, be sure to replace the filter/drier canister in the system, and evacuate it to at least 500 microns. Good luck!
