It sounds like something that's in the fan's settings. On your thermostat there will be a setting for an automatic on/off setting for your fan; you're going to want to double check that that's enabled. If it's not that is likely what the issue is, and would explain why the AC doesn't shut off.

If you check and it's already enabled, then the next area I'd turn my attention to is the wiring. There's a good chance that if the things aren't working the way that it's supposed to, there's some faulty wiring.

Check your grounds and all your wiring connections, and make sure that there aren't any broken or damaged wiring. If there is, just replace as needed and check again.
