My cooling fans will not come on no matter what.

My car reads a code of coolant temp sensor cicuit #1 I have changed both sensors one on top of the engine and also the one on the bottom below the passenger fan. The fans will still not come on. My ac works but my fans still will not work we have tested the fans too see if they do not work but they do. We have checked the relays to see if they have continuity and they do except for one prong. When everything is plugged in you can see that they fans are getting power but for some reason they are on turning on and so my car will over heat but as soon as I start driving or if I turn on my heater it will cool it down. My dad also stuck some wires into the relay and now my ABS light came on and I do not have ABS is that a fuse or a relay to fix that?
