Nissan Altima 93 temperature

They have already checked button and is fine, also the sensors only that the fans work when passing from half and wanted to know how they fit to function in half, and with the revolution it goes down almost zero and sometimes Hata has been off.

What possibilities is the bad computer for the computer ????

Look if it has 2 fans, check the engines if each engine has four cables, then handle 2 speeds each engine and official, the first entry into the normal operation of operation and the second to 3/4 of the engine temperature ap´roximably, if only the second of the fans 2 very common probable causes would be, the first the fans burned the first speed of both engines, the second a bad relay in this system is 3 Releases to see the changes and locations in the engine compartment, well you tell us later how it went greetings from Cancun

The computer does not control the actions of the fans in your vehicle brands like Craisler Yes, now it is not likely or feasible that your computer is bad, that is not the problem.

Look that I already check and if the fans have four cables and if it was signing, because the relays are well and they are fine, then the problem will be electric with form to the food of the relayers, at the time my query is who is what makes them work at the time the temperature rises ????

I have an Alfa Romeo 155 of the year 1995, my intrigue is that every time I use it does not lower the temperature of 90 degrees, no matter how much the radiator fluid changed and placed antifreeze, send the radiator to clean the radiator, but the same is still not low from 90 degrees of temperature, my query is whether it is normal that it works in that temperature?
