Why does my cooling fan run constantly?

What is your question?

Cooling fan runs constantly when engine is running. When I shut car off cooling fan continues to run for as long as 10 minutes. Temperature guage and info center both show zero. Fuse for cooling is good. Does''t have code or check engine light. Have car scheduled in to mechanic but would like to avoid if is simple repair.

How long has your 2016 Chevrolet Camaro had this problem?

About 5 days.
