My A/C compressor doesn't turn on. I checked the fuse and replaced the relay to get the cheapest issues taken care of first. I see in the WRX manual you can see if the A/C compressor signal and A/C switch are ON or OFF. I am wondering if you can read this data with any free software. I looked at the diagnostics in Enginuity but they don't have anything for air conditioner or compressor. Do any data loggers read this data? Has anyone used a Subaru Select Monitor emulation of any sort using a tactrix cable? Does anyone have any tips for testing my A/C problem? I have never taken a car to a mechanic because they are a rip-off, so any help fixing this would be greatly appreciated, thanks!

look under the switches in Enginuity/RomRaider's logger -> its there. It is not in the main list of parameters, but below it.

Oh okay, thanks. I'll use the logger for the first time tonight and see what I can figure out. I should have figured it was in there. This forum makes me feel like an idiot.
