2002 Honda Civic radiator fan not running

Hi,

The radiator fan is not runnning, and the water temperature gauge on the dash gauges is running a bit higher than normal. Does this sound like the fan thermal switch should be replaced, or would this be a thermostat replacement issue (or both)? Thank you for your help.

PS. Not sure if this is related, however I had driven through some deep water (flooded road) prior to this happending, and I imagine that some of the fan wiring got wet.
