the only fan relay is behind the passenger headlight.......i bet you have a faulty fan relay...tell me you didnt buy it from autozone....or advanced......i bought one from autozone...didnt work.....than went to the chrysler dealer and bought one for like $60 and it works perfect...the fan should come on around 220 degrees

probably because it wont turn on until the engine starts to overheat, BMW has the same thing, sensors on radiator to kick it on when it is WAAAYY too hot,,
does the car run hot? if it does and you are certain when the AC is on that it should be on, then it could be your AC Switch doesnt give the relay juice,

It is normal for the cooling fans to run on for a few minutes after the vehicle has been turned off. If the fans NEVER shut down you may have a faulty fan control sensing unit.

Considering you've tested everything else I'd say that's what your down to. Before you go crazy I'm pull out the continuity detector and make sure all your wires are in tack - especially the grounds.
