2002 Avalanche AC

Hi, my avalanche ac is not working correctly. The ac is not cold at all and blows out hot air when it stops. I refilled it with freon and it still doesn’t get any colder. What might be the problem? And also even though I turn the ac up high, it doesn’t blow very hard. (I used the gauge when refilling freon, so no overfilled).


There are too many possibilities to even venture a guess. You need an AC shop not an online forum.

Automotive AC is not a DIY thing. Take your Avalanche to a shop that specializes in automotive AC, and let them fix it.

Ok thank you for your suggestion. I will do that.
