WHAT WOULD CAUSE A/C SYSTEM TO INTERMITTENTLY GO FROM HOT TO COLD ON THE DUAL CLIMATE CONTROL EITHER SIDE AT ANY GIVEN TIME? IS THIS A COMMON OCCURANCE?

If it seems to be random, it may have something to do with an interior temp sensor but it would take a professional scan tool to see all the data and run tests.

WILL THE MASTERTECH READ IT OR DOES IT HAVE TO BE A FACTORY SCANNER?

The Mastertech is actually a clone of the factory scan tool but they cost over $10,000 so I doubt we are talking about the same tool.
