Default 90 radiator fan

I have a 1990 Audi 90 quattro 20v that the radiator fan is not working properly. When the car gets hot the fan does not come on. If i give the blades a spin by hand the fan works like it should. Does anyone know what the problem might be? Dirty fan motor or relay? Any info would be appriciated. Thanks in advance.

More than likely the motor. I don't know if it's possible, but see if you can check the brushes if it's not a sealed motor.

I agree. If a relay then fan would stay on all the time.
