Update:
I took the truck and had the ac serviced Aug 4, and I asked to keep track of the operating pressures while charging the system, but he did not do that for whatever reason. Why is it so hard to get anything done the way you want it today?

Center vent temperature reads 41°F at an ambient of ...

lol

Is that crazy or what?

Now that I have got the system working, and quite sure I do not have a leak, I am happy with the results. I have an appointment to have it evacuated and recharged by my local ac guy just for assurance that all is as it should be.

I did not pay attention to the readings, I was only going by amount of refrigerant.

It could’ve taken the full amount, but I wanted to make sure I didn’t put too much in. That temp is with the truck sitting in the drive.

I charged it only the low-side service port, cans upright for refrigerant gas, engine idling, windows open, system set to Max Cool, temperature set on full cold ...

Cusser:
The center vent shows 50 degrees on with 88 degrees ambient and a whole lot of humidity. That is sitting in the drive after running for 15 minutes.


Tim:
I will check the inlet and outlet pipes on the evaporator core to verify.

I want to thank both Tim and John for all of your help and guidance. You guys have been super and I appreciate it so much.

I was able to squeeze in a little time to get this project completed, I hope.

I checked all a/c related fuses and relays, all good.
I used 12 ounce cans of refrigerant and weighed in the charge. I got 31.3 ounces in. The truck calls for 33 ounces.

The questions I have:
How much of a difference in ...

Here is my next plan of action: (the truck is a non running truck at the moment and the a/c system is empty)
I plan on puffing in some 134 on top of the vacuum, and use a leak sniffer to check for leaks.

With the two hand valves on the manifold closed and the micron level stabilized, I will remove ...
