Re: How to wire electric fans to stay on for a few minutes after engine is shut off?

If you want them to stay on, you will probably need a delay like gmachinz mentioned if you want to keep your existing circuits.

You could buy a temperature control device like others have mentioned.

If you want, I can post a guide on how to make to a circuit interrupter that opens your switch ground so that the fan turns off with the key. I had to do this with my setup, otherwise the fan would run for about 15 minutes after I turned the key off.
