I need help my cooling fans stay on when the car is turned off.

 

That's nice.

What year/model rx7?
What mods does it have?
When did it start doing this?

 

Aftermarket fan? Has it done this since it was installed?

If so, then it is probably drawing power from a source that is "always on", like the battery. What you want is a power source that is only "on" when the key is on.

its a 1993 rx-7 only mods done are greddy intakes, downpipe and hks hi power. after a drive today the problem disappeared.
