AC compressor cycles on even though AC is off...?
I have has this issue for awhile. My AC compressor is cycling on and off even though the AC and recirculate buttons are off in the cab. I am running LS1 fans with a Nelson tuned PCM and fan harness, so one fan is coming on high when the AC compressor clicks on. I can't help but think that this isn't good for my gas mileage. I rarely use the AC. I am not sure if this was an issue before the efans or Nelson tune. Model and other mods are in sig.
Thoughts? Thanks!

I have also noticed that my low-speed fans rarely come on. In fact, I have NEVER seen them on in the two years I've had the LS1 fans and Nelson tune. There have been a couple instances in heavy traffic on a hot day where the truck started to overheat, so I turned the AC on to get the single high fan to come on and bring down the temps. Perhaps these two issues are linked?

You could also go to the 2 pin harness which is not spliced into the AC compressor.
Check your relays and wiring though. I had one relay get corroded after only a couple of months and I almost overheated.

As terravast4 mentioned, they did it to condition the cabin and remove moisture in the air, many different manufacturers do this. I agree that it's unnecessary for many folks, especially performance enthusiasts, but the normal Joe like breathing clean dry air I suppose
