Default Auxiliary Fan issues

Howdy All,
I hope all is well. While gearing up for the summer months, I noticed that the auxiliary fan is not functioning. I jump tested the fan on the battery and it worked. I replaced the two silver relays in the fuse box (I believe they are the center two of the six in the fuse box. I understand that the car needs to hit certain temps for the fan to engage, low speed and high. However, I was told that the fan should come on as soon as the AC is turned on. Mine did not. Any help would be grand!

ForcedInduction,
Many thanks, I will warm her up today and see if it runs. Also, should it come on at key position 2, after 10 seconds? Like a diagnostic check. I have that in my brain for some reason.
