so about this time last year i topped of my fiance's cobalt with freon only(no oil, when i used to be an autoparts slinger i was always told never add oil to the a/c system unless you are doing a complete drain), it had a slight leak from what i can tell, the coldness of the a/c was very weak. so fast forward to last week now, she had said the a/c was weak again. i got my can of freon and my gauge and had her crank the a/c to max. the gauge was coming up low, i filled it until it was in the acceptable range and voila the a/c is pumping out ice cold air again. Pumped out the ice cold air until Friday. I hit the a/c button and the compressor is not kicking on. The blower motor still blows strong and works on all settings so its not a blower motor issue.
I checked the a/c related fuses, the fuses looked good but i replaced them just in case, still no good. I then drove the car and made it heat up to 223 degrees when the fans kick on to make sure the fans were still operating. The fans kicked on right at 223 just as it should. Next i'm going to replace the a/c clutch relay and hope that this fixes it. If that does not fix it, what else i should look at next? i know enough to be dangerous with a/c issues.
