Check all your fuses using a test light. If they are good, then someone is going to have to troubleshoot the circuit using a test light and a wiring diagram.

Check and test the coolant temperature sensor if okay -have the computer circuits for the fan relays-checked and tested

If it doesn't come on with the A/C, you can probably eliminate the temp sensor as the problem.
