A/C fully charged but not very cold
My 2002 has never had the coldest A/C. It's also never had refrigerant added. Phoenix is especially hot this summer so i figured I'd try to add some refrigerant and hopefully improve the situation. I bought one of those cans with the gauge and hose already attached and when I hooked it up, the needle was at the far end of the green showing a fully charged system. Is my A/C system just not up to dealing with 115 degree temperatures or could there be something else?
FYI- I replaced the power steering cooling fan last year so that's not a concern here.

i have an 03/2012 build cms all4 ... many cm owners are complaining about weak A/C
if i keep the rpm above 3,000, i get 42F air out the vents on a 100+F and very humid day
if i let the rpm drop to 2,000 rpm, i get 70F or higher air at the vents
the R134A A/C systems are not as efficient as the older R12 systems were and the extra rpm helps a bunch
