I think it's the blower motor, but here's what it's doing: When I turn on the AC (or vent or heat) sometimes it works perfectly, sometimes the air doesn't blow at all but the compressor is turning on under the hood. After a few minutes the air will start to blow and it may or may not stop. The rear air always works perfectly. Thoughts?

 

when you have the heat or air on even though it doesnt blow anything out of the vents, does the front heat up or cool down? (you said the back always works) or does the temp change in the whole car or what?

 

Nope, interior stays hot as hell. I guess the back seat area stys somewhat cool.
