Check out how your airflow is set. If defrost is set ac may not work

What you describe is what happens when the outside temp. is below about 38* which prevents the evap. from freezing up. Assuming your outside temp. is above 38*, then it might be the sensor. Mine on one occasion did what your's did and the temp. was 65*. Never has repeated.

Default well.

step1:

Stop typing in all caps. it's rude and hard to read. (considered yelling)

step2:

check things like the A/C charge level, see if all the fuses are in tact, see if there is a large hole under the hood next to the engine where the a/c compressor used to be. Does the compressor spin when you engage the A/C?

step 3: if you want to do it your self, read, learn:

http://www.wikihow.com/Fix-Your-Car's-Air-Conditioner

Read the article, but the video is crap.

2000TAHOE,

I am sorry to hear that you are experiencing this issue. Have you spoken with your local dealership to confirm the issue?

2000TAHOE Welcome to the forum
I would check to see if the compressor is coming on when you enable the AC as it may be low on refrigerant...
