Making A/C operational without PCM???
Who can make it happen for me? I have this
But it doesn't really mean anything to me. I don't want to run a toggle switch or anything like that, I just want to turn my **** to cold and, BOOM, A/C. The vehicle is a 2007 classic silverado. Thanks

Is this is a retrofit or an ACTUAL 2007 Silverado. If it is the latter, where is the PCM?

I guess I should clarify. Why do you want to get it to work WITHOUT the PCM?

If the HVAC control integrates the temp (thermostat) control and is 12V, simply route that to a trinary switch then to a relay that powers the compressor.
Or you could route the output of the hi pressure switch thru the low pressure switch then to a relay that controls the compressors.
You need to confirm the HVAC output is 12 V and not a data signal either way.
