trying to put my ac on today and the ac button just keeps flashing and wont stay on .blowing hot air any suggestions what it could be

 

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

 

I have no idea it didn't work for like 2 hours after shutting it down now the snowflake button stays on and the ac is working really weird to me.

 

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.

 

utz, if you run into this issue again let me know and I'll do what I can for you on our side of things. I hope you ahve the same luck with it as 73shark.

I HAVE A 2000 TAHOE THE AC BUTTON HAS BEEN FLASHING FOR MONTHS WOULD STOP WORKING ANDTHEN START BACK UP. NOW IN MID SUMMER IT STOPPED WORKING AND JUST BLOW HOT AIR. I HAVE A 3 YR SON AND IT IS GETTING UNBAREABLE. DON'T KNOW WHAT ELSE TO DO

 

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:

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?

Thank you

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...
