My cooling fan does not work randomly, i was check with a multimeter the voltage in the connections, and this what a got. at start 3.2v, with the ac on 2.3v, when the car is at 99°c 3.0v when the car is at 97°c 3.2v, at 102°c 2.3v and 104°c 1.1v. i was doing tests so i accelerate a little and the fan just stop it was a 100°c, so i check and it was a 3.2v and reach 105°c. i turn off it and back on and everything work again. the 4th time i reach the 104°c the cooling fan kept going. it was like 92°c and i check and the voltage was 3.0v. so i tried another cycle to 104°c and the next one the fan kept working but this time is was a 2.3v, it went down to 92°c and change to 3.0v and stayed there so the temperature was 88°c. i tried to turn off and back on a couple of times but the fan kept going. so anyone have any idea what could be wrong
