After all my diagnostic work, I couldn't find anything malfunctioning other than it wasn't cooling after everything got hot after a shut down. I added just a couple of ounces (1-2) of R134a and it is cooling very well now. I still don't understand why it would operate fine (32.6F out of the center vents) even in 92F temps until I shut if off. Maybe with the R134a being on the borderline, as the the temps went up it was not able to cool at all. I know the amount of r134a in the system is critical to it functioning properly. A lot moreso that R-12, you could be a little above or a littel underfilled and it would usually still cool just fine. I've been running it for the last few weeks this way and it's been cooling great even after very hot shutdowns.
