The radiator fans on my car as well as all the daytime running lights remain on even after I shut the car off. I changed out the 3 fan relays with some autozone ones and the problem went away for about a week and they came back again today after I parked my car at work. I disconnected my battery as soon as I saw what was going on so that the battery doesn't drain and then I reconnected it back but as soon as I did the fans and DRL came back on so I quickly disconnected the negative cable. I proceeded to do it one more time to see if I could start my car even though the fans and lights were on but it just clicked and died and everything turned off (no crank at all). I then disconnected the battery and the top relay for the fans and connected the negative cable again and the fans didn't turn on but the lights did, but I did manage to crank the car and it started with no hesitation and I connected the relay back and drove home. As soon as I got home i turned the car off and the DRL came on the fans kicked on too so I just disconnected the negative terminal again and just left it that way. any thoughts on what it could be before I take it to a mechanic?
