Bought a 2004 Spectra EX in February with 83000 miles on it. No problems so far until last week randomly my AC stopped working and blowing. It started intermittent but now when you turn the knob nothing happens. Not sure what the issue could be but when it was intermittent before it stopped completely it sort of made a low buzzing noise when it would work. Not a big car guy so not sure what the issue is but is very hot out and need my AC. Fuses check out fine and had the fuse box checked to make sure everything was good and it is. When I turn it on if I put my hand right at the vent I can feel cold air barely coming out but don't feel it. Any suggestions would be great.
