Cooling Fan 1 Control Circuit

[Brando56894]

my car keeps throwin a SES light, i have one of those carchip things that records stuff and the error code says Cooling Fan 1 Control Circuit and the code is P0480. i checked both fans by powering them directly and both of them work fine. I checked the fuses/relays and theyre both good, and the connections seem to be good, didnt really check them in depth. i also tried clearing the code, using the carchip thing and it went off and stayed of for say maybe 20-30 miles then came back on. i was j/w what u guys thinks could be the problem

cleaned all the grounds, or all that i could see. thats how i found out i have daytime runnin lights the chick that owned the car lived in egg harbor twsp and worked in AC so theres all corroision from salt and **** in the engine bay i managed to clean most of it up, but its a pain in the ass. well yea i cleaned the grounds up and my dad was like "Bran, your lights are on." and i was like "uhh no there not" and he was like yea they are" and i said "no there not the switch is turned off" then he was like "oh, you must have DRL" and other suggestions?
