I wasnt sure, but on my 98 Catera i tried using the AC 'cuz its gettin warm, and i got warm air; not cool. I even let it run for about 10 min.

I pressed the "AC" button and on the display it says "AC" then under it the "Off" appears like the heating would be off? I turned the knob all the way down to 60 degrees, but it's still warm. Not very "cool" at all.. Haha.. Get it..

Anyways, any help would be great. Thanks.

You need to hit that AC button one more time to get rid of that "off" symbol. If it keeps on blowing warm air then you need to get the system checked for charge.

Yesh. I tried that. I think it needs checked. If I press it again the AC and the OFF turn off.

Hmm.. Grief..
