AC after Hose replacement

[2018ExpyPlatinum]

I've never heard anything about this TSB. I'll have to look into it. Mine is a bit weird. It runs it's normal meh most of the time, but lately, sometimes its run pretty cold. No rhyme or reason. I always have my rear AC set at 70-72 and on.

Interesting as I did some common sense detective work and ours works better if the rear is on. If the front is on by itself, it blows cool air not cold, as soon as we put the rear on both blow colder good but not great. Weird.

Following - my 2020 had same symptoms but now blows hot all around and measures low pressure. May purchase my own evac rig and service myself. Thought about going to r134a, who has done this? Will look for a thread....
