Request an A/C Pressure switch diagram

2008 Rondo, 2.7 V6 A/C cutting on and off. When the compressor kicks On it blows cold. Then for no reason we notice the lights are on but the compressor is off and the air out of the vents is warm.

So I think it is possible the pressure switch is intermittent? I also would like to check the compressor for low Freon too; but ....... From what I gather the pressure switch is a "combo" Low, Mid & High setup (correct me if I'm wrong).

To test the switch does anyone have a wiring diagram so I can jump the Low contacts to get the Compressor to turn on?

Does anyone have troubleshooting tips?

Thanks Byron

UPDATE: I eventually found my service manuals I downloaded before the web site shut down, so that got me started. But I ended up unplugging and plugging the pressure switch and compressor connectors a few times and NOW the compressor only kicks off once in a blue moon; not like before. IN DOING SOME REASERCH, I also suspect one of the temp sensors might be out of range I.E. the condensor sensor goes out of range when it gets cold shutting off the compressor.
