125,000 miles. Air Conditioning stopped. Clutch engages & engine revs normally.

What is your question?

2003 Saturn LW200 with 125,000 miles. Air Conditioning stopped working suddenly. Clutch engages normally as well as engine revs for air setup. Even secondary fan starts as well. But no cold air. No signs of oil on engine or floor of garage. Will running the air conditioning pump ruin the system? Not turning the air on for now, but do need it on hot days. Fuses seem ok as well. Thanks!
