Electro fan doesn't turn on when it passes 90 degrees
Hello guys, let's see if someone can give me a hand. I have a 20d n47 and for a while the electro has not turned on, however when I turn on the AC it does go, I have changed the coolant sensor because they have told me that it can be because of that and nothing, it goes up to 90 degrees and it does not start either, removing the temperature sensor if it starts. Could someone give me a hand?

Does it overheat? No need for the fan to run at operating temperature. It'll run with the AC on to draw air through the AC condenser, regardless of engine temp.

The operating temperature is 88 degrees. It should turn on at 89-90 as before, now it doesn't do it anymore, I changed the coolant sensor, water pump, thermostat, it's still the same, this one doesn't turn on
