My C7 3tdi Cooling fans don't work. Codes and live data cheked and all parameters are ok. I can do the output test but still they dont work. I see live parameters and they takes power when engine gets warmer or i turn the a/c on but still they are of. Fuses are ok under the hood. What next? Are the fans working if a/c pressure switch or pressure sensor didint work? All engine temperature sensor give me information and i think they are ok. Sorry about my bad english😄

The cooling fans themselves may be the problem. You can test the fan motors by supplying direct power to them from a separate power source, such as a 12V battery. If the fans do not spin when supplied with direct power, they may be faulty and in need of replacement.
