Hello everyone, I have been getting this fault indication for a while now: "Failure of engine comp. blower fan" on my 2005 997 C2S. It comes on with a beep and the red light on the coolant temp gauge starts flashing. It seems to occur whenever the fan should/does kick on while driving when it gets too hot.

I have already replaced the fan because the housing was cracked/broken. That made no difference. Then I pulled out the temperature sensor on
