I have a 2006 chevy cobalt and two weeks ago my AC just cut off. It would come back on with a funky smell then cut off again. But last week it cut off and never cut back on. We replaced the freon last month and it was cold. The heater won't blow out air either. We checked the fuses, all good. We checked the relay and that was fine. I need some desperate help. If you can think of anything else I can try to figure out what the problem is please let me know.
2006 chevy cobalt AC will not blow any air on 2006 Chevrolet Cobalt
If it is blowing any at all, or if you can hear the fan, you might want to check the cabin filter. Accessible through the glove compartment.
