A/C ok drivers side but only on/off passenger's side (P0483)

I agree with the blend air door issues on these era Rams. however an easy and more possible fix may be an evac and recharge. when the system gets low, because of how the evap is designed, the drivers side will get cooler than the passenger side! recharging the system may fix the issue. I`ve ran across this problem on different car lines and the majority of them were fixed with an evac and recharge!
