I to am having an a/c issue. I have read about the blending doors not closing fully. Dirty radiator ect. Pinching one of the hoses to see if the problem is solved. My ac blows 59 degrees right at the middle vents on high recirculate. What is the temperature at on high?

I dont know any temps or anything in my Ram I have the ST trim so its barebone as they come (I'll be upgrading to laramie longhorn someday) but as for right now i can say i definetly need to clean under the hood but I dont know if that will help my a/c get colder when i get the chance im going to double check the freon lines for leaks.

Not being a smart ass but it's the thing that looks like a radiator in front of your radiator

You will fine. Use air or a water hose to blow the debris from the opposite side. Or use a bristle brush to remove all the debris

Just don't fold the fins and you should be fine. Should see a big difference. If that doesn't work find someone with a/c guages with MV hookup and check the charge.

That's the next thing I was going to say. They are very overlooked.

My AC sucks in my 17 RCSB . My G6 will freeze you out but this truck isn't the best. When it's on recirculation and the outside temp is 81 , I shouldn't need my AC on full blast to cool my cab down.

I would still focus on the airflow first. Then maybe check to see if it's the 65+ or if it's because of the sustained higher rpms. I can only assume whoever did your repair got everything tight and did a good evacuation of your system before recharging it .

If there is an electric cooling fan for the AC system, make sure it runs when the system is running.
