good afternoon i am master tech and will be able to assist you.

can you tell me if this acts like the ac was turned off and then after about 10-20 minutes it will start to work again but not as effective until it has a longer time to cool down ?

Customer: replied 2 years ago.
That is what it was like, but a couple of days ago one of the guys at worked recharged it and it still did that for 2 days. However, yesterday and today it just blows warm or hot air now, no matter what.

ok sounds like this has a failing expansion valve. pretty tell tail signs this is the reason for asking.
as the ambient temperatures rise the more often it will happen.
the expansion valve will actually freeze up and it has to thaw out.
can you tell me the a/c low and high side pressures ?

Not a clue. I'm a 75 yr old widow

here is a picture of it have him see if it moves when the temps are moved from hot to cold just want to make sure we are not dealing with a bad air mix motor.
