2001 Chevy Cavalier. The first two fan settings do not work at all, only settings 3 and 4 work. Also the AC isn't the greatest but I think it just needs cleaned.

Ever since I owned the car(bought in Feb '06) the Heater and A/C never worked correctly. No matter what setting you put it on, it only blows air out the dashboard vents. It will work out the windshield vents if you push the A/C button, whether in heater mode or A/C mode. If you need to defrost/defog the window, you have to put this on to get the stuff off. Very annoying. Anyone know what this problem is? I will be researching it and posting the fix if I find it.

well, I have a 2001 Chevy Cavalier and the first setting of the heating dial doesn't work...you turn it to the first one and no heat comes out...what a piece on s&%t
