Good luck

My fans (SPO 2811) come on around 85C and keep the engine cool...no problem, both work and suck air in...when I turn the engine off the fans will come on and then turn off when the water temp gets to below 80 except on a couple occasions when I have gone back out to the garage and they were running at 60C...on a couple occasions, they have ran the battery down ??? I have a manual switch on the dash...I guess my question is what is your guess, the temp sensor or the relay or what ??? If so, where do I get the parts ??.....to tell you the truth, I would just as soon do away with the automatic feature and just use the manual switch but I suppose, nothing is simple anymore ?? Thanks in advance for any advice...
