^^^ If the fan is on, then you will need a new ECU as well. It measn the ECU is toast.
I really love my service department. They take care of me, and they have always delivered really fast. They are usually not extremely busy either.
When I went to pick up my car, there were two tech standing around waiting for work.
If your ECU is repalced, you will need to bring your extra keys with you when you pick it up so they can program the extra keys.
