2000 Monte Carlo ss temp gauge

I have had a problem for a year now that comes and goes.Now I think it's here to stay.Temp gauge reads nothing, A/C won't come on, and the radiator cooling fans stay on all the time.Replaced ECT sensor, still same problem.I'm leaning toward replaceing the PCM.Any other suggestions?
