2001 Saturn SC2 Question: HVAC fan on high with switch off

My HVAC fan suddenly went to high with switch off. It stays on high while car is running. Never changed/tested a relay before. Any help? -
Answer 1
Using a ohm meter (usually a setting on a volt meter), test prongs 86 and 85. If it read open, it is bad. Or take a 9 volt battery and hook it to these terminals. If you hear a click, it is good. If not, the relay is bad. -
