A/C getting hot while slowing down?

So, it sounds like it could be a temperature blend door actuator, I would start by turning the A/C on to full cold settings and then feeling the A/C low side hose coming out of the fire wall, it should be cold. if so, the temperature actuator needs to be replaced and if not, I would check the charge of the system. Check the images below to see what the hose I am talking about, and I have included guides as well.

Here is the temperature actuator as well. Please let me know what happens.
