You need a test light or DVOM to perform testings, not by replacing everything you can think of.

First of all you need to understand the system and how it opearates. Next you check the power source and relay controls.

Do the fans operate when the relay terminals are bridged?

That mean either the relay is not getting power or there is a break between the relay and fan motor. You need an electrician, seems your mechaninc does not under electrical circuits.
