First I would just like to take a moment to thank everyone for there quick response and great advise.
I believe in my situation there were 2 things going on. Both solutions where in the responses to my post. Number one problem was the outside temperature was too low to engage the AC system. Problem pointed out by 2seater, thanking you. Padgett and Ronnie thank you for the detailed answers and visual aids.
Next, I did have to clear the codes by disconnecting the battery, jumping the low sensor to engage the compressor and added AC oil, sealant and freon. Needed to do these steps multiple times because there was zero freon psi.
Finally, AC working and owner happy !
This can not go unsaid, I could not have completed this job without all the help of the Forum members.
Now on to my next Reatta project.
