Crazy thing. I was coming out of the gym and started my truck and noticed the temperature lights and controls flashing. Can anyone help?

Thank you

 

I've never seen a thermostat with lights...

 

Do you have an aftermarket alarm system? I know my mustang would flash everything inside including the climate controls you’re referring to. It might have something to do with a normally open relay staying closed for second before you start the vehicle or disarm it.
