Radiator Fan stops spinning after startup

So my check engine light came on and in an attempt to see what the cause may have been, I discovered that the fan on the radiator stopped spinning. I thought it would be a blown fuse, so I replaced both of the cooler fan fuses on my model. The check engine light still shows, but I noticed that after turning the engine over, the radiator would stop spinning. I assume that if I were to hold the starter down that the fan would still run, but obviously that's bad for the car. Since the fan still turns, I assume it's still in good working order; I have no idea what else the problem could be aside from a fault in the wiring. Perhaps I am replacing the wrong fuses, or I need to replace all of them. Any suggestions before I take it to the shop? Thanks!
