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?

It's an actual 2007 classic silverado. The pcm in the engine compartment

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

Because I'm making the change to carburetor and have no use for the PCM anymore other than apparently the A/C lol

I have an MSD 6010 ignition, I'll no longer have cruise control and I have a full manual 4L80

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.

The HVAC head unit will send 12v for AC request. Use it to trigger a relay to engage the AC clutch. It would be a good idea to integrate a pressure switch on both the high and low sides, but not required
