If this needs to be posted somewhere else move it or tell me where?

I'm not very good with A/C units and there web site is a pain to find things.

Somewhere I was reading and my understanding was that your A/C may or may not freeze up and this switch is a fine tune switch under the dash somewhere, set it and your done.????????????? wire diagram (top left "A/C Thermostat") or what part # is it??

"Control Module" (bottom center) is this the "Control Panel" or what is it???
