This isn't going to be as simple as asking someone online. It's an intricate circuit and someone with electrical knowledge is going to have to do some testing. https://www.2carpros.com/images/external/79005043.jpg.gif

Which sensor? The coolant sensor? I am having the same issue. I replaced with new fans/motors/relays but still not working. Which and where are the fuses located? 1998 Sentra ga16de, GXE, automatic.
