I attached the wiring diagram. Can you remove the relay and turn the engine on and A/C on and measure voltage on pin 4? Then you need to check and see if the PCM is grounding the relay on pin 3. You do this by checking for ground when the AC is on. Put the red lead of your meter on the positive battery terminal and then put the black lead on pin 3 of the relay. With the AC on you should have 12 volts on your meter.
Let me know if you have questions. Thanks

Did you check these with the key in the on position? Specifically pin 30? This should have 12 volts when testing to ground with the key on. If not, then we have a possible fuse issue but I think this pin shares the feed with the same fuse the fans work off of. Do the cooling fans on the back of the radiator work?
