[DML] Re: Fanzilla Failure???

["Steve" <steve@xxxxxxxxxx>]

OK, It does seem to be the Fanzilla that failed. I pulled out my 
workshop manual to figure what wires are what and discovered the two 
power wires that go out to the fans. Only one is getting power and I 
tried swapping the fanzilla fuses and it made no difference. I 
noticed the fanzilla unit is hot and seems to be a bit deformed from 
the heat and seems to have something that rattles inside. I don't 
know what the warranty is on these but I guess I have to get a hold 
of Rob to find out.
