That's not nice. The error is me personally?
I came up with hundreds, literally hundreds, of sources that said my numbers were correct. It was amazing. Everywhere I looked I came across sources that confirmed my numbers. I couldn't find a single source that said your numbers were correct. Not one! I couldn't figure it out. Even other manufacturers like Ford and GM. Seriously. None! I even went to my super old Haynes manual #1480 printed in 1989, Automotive Heating & Air Conditioning Systems... It also didn't agree with your numbers on the chart (for R-12). I was almost content to just leave it at that, but I wanted to know how the numbers you gave could be so off. So, I did some digging on exactly what a freon temp/pressure chart is. You have incorrectly interpreted the chart. You even bolded the misinterpretation!
Your numbers have nothing to do with this situation. You have referenced a chart that is for resting freon temp and pressure. That's why none of these numbers add up. It's not low side/high side, it's for a system that is not running and the two sides equal. It's true. I bet you could e-mail Fluke about it.
But in the mean time, I found lots of confirmation about this issue and I even confirmed this with some HVAC guys on another forum I'm on. But here is a nice Internet site that has the information: http://www.instructables.com/id/How-...1/freon-check/ Of course you don't have to read it, but at least the information is out there now.
Perhaps that would be best.
Since you asked, I'm an economics student. I mostly do research and analysis on numbers.

im gonna let all you internet HVAC experts deal with the HVAC issues on here now

Ok, so the pressures on my high and low sides were about the same (running or not). The A/C light was blinking. I replaced the clutch relay ... still blinking and no cold air. I went through one thing after another and everything pointed to the compressor clutch ... it just wouldn't turn on. I thought it could have been the clutch switch, but I hadn't a clue what it even looked like.
Finally, I just started staring at the compressor and noticed a loose ground wire. Yes, it was a loose ground wire that I'd not tightened enough from when I'd recently replaced the water pump. Tightened the screw and clutch started turning and, suddenly, nice, cold air!

NICE!
tinman is 100% right.
sakataj, what tinman said about automotive ac pressures being higher is correct. And just because you've been doing something for a long time doesn't necessarily mean you're doing it right.
You obviously do not work with AUTOMOTIVE air conditioning.
