Couple of things to check. First is the coolant temp sensor. If it reads hot all the time the fan will stay on. Most common is a code set in the engine module. The fan staying on is a failsafe due to the code. Local auto parts store should be able to scan it then Google the code. You'll prolly find a YouTube video to tell you how to fix it.
