You might have a bad temp sensor in the intake manifold.

If you have the AC on all the time the fan/s will run all the time.

I don't know if they're both running, but it's on whether or not I have anything running in the car.

Try a different fan relay (actually there are 3 involved) the contacts may have gotten welded toghether.
