My daughter told me the a/c had stopped working. Initially I though that is was low on freeon, it's full. The compressor clicks on and stays on but the engines fans do not come on. I checked every fuse, they are all good. Swapped the relay for the horn relay wish is the same, no results. What else should I look at.

No offense, but is the A/C "full" of freon because you found it that way, or did you add a can without checking the pressures? Possibility exists that the high pressure switch is open/bad, or even that the compressor has failed internally. Need to get some pressure readings posted before going further.......
