This sounds like an A/C control issue, in that the Climate Control Module is what turns on the A/C. I would carefully inspect your A/C system and Climate Control.

I was told that an A/C Evaporator Temperature Switch is causing me my problem

Had a similar problem in an E38 BMW. A switch was not allowing the compressor to cut in. But this was a pressure switch. The refrigerant has a lubricant in it for the compressor. When system pressure is too low from leaking, the switch breaks the circuit to save the compressor from running without lubricant. The solution in this case was re-gassing.
