Default ac needs help

hello all, I am very new here so here it goes. the ac to my 06 H3 has issues blowing cold air when it is hot outside at night I have to actually turn it down cause it gets too cold LOL. I have recharged it, replaced and ambient sensor that is in the front by the grill and I am at a loss.

I recommend a stop at garage of your choice and have an inspection of full system.

Do you have an AC Pressure Gauge? Is your system overcharged?
