First off, replace the fuse rather than check it.
For diagnosis you're going to need a wiring diagram.
First thing I'd do is wire directly to the fans to check that they are okay. Then I would find the temperature sensors that control them (usually one for switching on temp, and another for shutting off temp).
Did you try your AC? One fan should go on when the AC is on. If it does, this suggests to me a bad sensor.
If the fans check out okay with hotwiring, but won't come on with AC, or after grounding the sensors, then you have to search for the relay, which should be in a relay box under the hood somewhere. I'm sorry I don't know your car well enough to locate it but I think it's a box on the firewall, on the engine side. There should also be a schematic of these relays and fuses in your owner's manual, if you have one.
If you don't have one,
