fan

so my fans on the rad stopped working. So far I've swapped out all relays and and checked the fuse, spun fan by hand and boosted it DC . Fan motors ok. Been getting p0480 p0481 fan one and two controls circuit. Any ideas anyone?

I have a 2004 Saturn Ion 2.2. The cooling fan fuse continues to blow. I replaced the fan about a month ago and it worked until a week ago. I changed the engine temp sensor as well. Any ideas on how to troubleshoot?
