A/C issues 2015 CM

So I’ve searched the threads about the A/C blinking light issues, as I had that issue on my way home from the desert today and never had any other issues before. Stopped, replaced the mag clutch relay, as I’ve seen the threads on here about it, and then drove off thinking it was fixed, as it initially started blowing cold again, but as soon as I got on the highway, it started blowing hot air and blinking again. Now here’s the odd part. If I was in traffic at low speeds, it blows cold as hell on full blast no issues or blinking for miles on end, but once I speed up it starts blinking and cutting off the A/C again. I was able to set it to a lower setting eventually and keep it on, but in full blast it blinks again. Anyone have any recommendations or ideas as to what it could be?

 

Also, it kind of smelled like refrigerant in the cab when it would cut off too, so not sure if that helps. It would go away when working though.
