KerryKool,
I don't think they will replace it free as it is 10 years old. But you could try asking and see what they say.
As for the fan harness, that can be purchased individually for about $200. Some CEGers have replaced just that.
However, you should check the connectors first. Then, I would also suggest opening the outer cover (of the fan harness) to see if any of the wiresis flaking off.
Edit. I thought you were going to do the moderndino zetec fan fix, or did that not help.
