Ok guys the $30 autozone fan controller has bit the dust. It just comes on and stays on. No more thermastat control at all.
So who knows of a solid, reliable fan controller that will last for years to come?

Yeah, it is $110...but it is best one out there and the customer service is second to none. I think his lead time is ~1.5 weeks.
Does the autozone one have a removable relay? It sounds as though the relay has simply stuck closed
