When the slide is moved to the left it opens the flapper to shut off heated air and open the air from the evaporator. It also has a cam integrated with the cable end that pushes a button on the AC switch. Just changed mine yesterday while putting in a new blower relay.

Thanks man, but it sounds like you're talking about a flap for hot/cold air control, while I'm talking about the automated switch that turns the compressor on and off.
Wait, I just thought of something that might make this all moot... Does the ac system used in these trucks need to cycle on and off, to keep the right pressure, or are they always on when cooling, no cycling? I might just be really dumb....
