The A/C works well most of the time, but when the outside temperature gets hot (95+), the A/C will no longer blow cold air. The air coming out is warm at best, but usually more on the hot side.

Any ideas?

the first thing that needs to be done is have the system evacuated, put on a vacuum and recharged with the exact amount of refrigerent then we can go from there. most likely this will fix your problem but you should also check the operation of the coolant fan clutch to make sure there is plenty of air flow through the ac condenser in front of the radiator. let us know how you make out
