The low speed should start at approx. 92 °C and the high speed should start at approx. 98°C.
If the car has AC, the low speed will also start when the condenser needs cooling.
In the low speed a resistor is put in series with the fan to slow down the speed
To me it sounds like the low speed don't work in your car.
I assume your car has two fans right?
It has seperate circuit for the too fans (relays and resistors). Maybe both of your resistors have failed.
Have you used MES (MultiECUscan) to check if both fan speeds work?
