ac button is a picture of a snow flake that should be lit up blue. it is hardly ever lit up.i had my ac charged and the motor went on the way home.had a new motor put in and tried to charge it again and and it still doesn't work.also feels hotter then it should be at my feet when i am driving.many more electrical problems too.

When I am driving in traffic with the AC on, it will blow cold air for a second, then blow hot air, then blow cold air again. It is very annoying so I don't use my AC anymore until I get it recharged. Hopefully that will solve the problem

My AC is not working I tried to recharge it myself but it still isn't working I wasn't sure if it was the really ofr or if I would have to get a new compressor. I would really like to keep the thing as long as possible. Can anyone give me a suggestion?

no heat in the winter! it's cold in ohio. changed the fluids - some heat - fans barely pumping out enough to defrost the window.

My cooling system works fine most of the time, yet it will occasionally stop blowing cold air. It will always work in the morning but seems to be affected by sitting in the sun for a period of time and will not cool. Also, we have found that gunning the engine will cause it to immediately start blowing cold air. The dealer as well as our usual repair shop cannot find anything wrong.

AC is intermittant. Sometimes it works, sometimes it doesn't. What a lousy made car. This is the worse auto I have ever owned. problem after problem after problem. I will never own a GMC product again. I spen more on theis new Blazer than I did on my 1989 Blazer with 165000 miles!!!!
