When using the fresh air vent with the temperature **** full cold, does system always seem a little warm, or is there something wrong with the temperature control? Thanks

Fresh air won't get as cold a recirculate.
but when in doubt, it's probably time for a recharge for the AC system.

I apologize, I did not word this correctly, I meant with fresh outside air only through the vents when it is cool outside. A/C not being used. Thanks for reply

Full cold with no AC on should be the same temp as the outside air.

...unless the car has been sitting in the sun all day. Then the air will be warmer than the outside air because your vents will be heat soaked.

If you just want the vents on for fresh air but hate the warm air that comes out due to heatsoak, turn the AC on for a couple of minutes, then turn it back off. That'll cool off the vents so the fresh air coming in is closer in temp to the ambient air outside.

If you ever have to, then you have a leak! They are sealed! The refrigerant does not
get old and does not wear out. Nope, if you have to recharge, then your A/C system is
faulty. Leaks will only get worse, never better...

Yes, because you're cooling WARM/HOT air, so it will only go down ~35 - 45 degrees from
what the outside temp is. On recirculation, as the air gets colder inside, it cools that cool
air, and dehumidifies the cabin. Dryer air also feels cooler. When you're pulling in the
warm humid air from outside, you're constantly condensing water, and still getting some
humidity in the cooler air. Recirc will dehumidify the cabin so there is a very low humidity
index.

What I am thinking is the Temperature select **** is not is not getting the mixer control to the full cool side. Thanks for all your input....

No argument there, but a $20 recharge will usually get you through the summer.
as opposed to spending $200 on a diagnosis and another $200 for the fix if it's easy, and then another $50 for the charge. Sometimes procrastination is not so much a solution, but a cheaper workaround while you save up the finances to do the fix... or trade in the car.
