I think I have the mazda fan mode done to my car but It never stays on after I pulled the key out. But one time it did for the 10 mins. Does any know or have this problem? Thanks

 

Mine requires two conditions for the fans to stay on for 10 minutes after shutdown. (1) The switch must be turned on for about 2 minutes before turning the engine off. (2) My engine
temperature must be above approximately 180F.
