AC Compressor cut-out due to high pressure/fan not operating

What is your question?

AC works fine as long as I am driving over 20-30MPH, or if outside temperature is not very hot. AC Compressor cuts out if I am stopped. I tested and the pressure sensor on the high side is causing the compressor to stop due to high pressure. Manual says fan should be running at least at speed 1 when AC compressor is activated, however, it does not, although at times it will run at speed 2 if engine gets hot enough. Should I replace Fan Control Module? My theory is that not enough air is flowing over condenser coil, causing high pressure. Fans should be running, but are not, but since they work on high speed (speed 2) I suspect a problem with Fan Control Module. Thanks.
