Cooling fan always on

Hi.

The cooling fan on my 89 420SEL is always whirling away, even with a stone cold engine after sitting overnight. Is there a way I can test the thermo-switch or coolant temp sensor (are they the same thing?) to see if it’s bad? Also, if someone could tell me where it’s at it would be helpful.

Thanks,
Clay
