It works sometimes and not other times, it **** the bed on me this winter on speed 5, all the others worked fine, now that it's summer it won't work at all, ac is cold just no air coming out, it's a 2007 chevy classic model. Any help would be great and is it easy to do and is the part I need expensive, thanks matt

Usually it is the resister for the blower motor. Look under the dash on passenger side.

there is a service bulletin from gm to replace the blower resister and connector if your vehicle fall with in the requirements. If you call and ask a dealer to run your vin number they can check. I have replaced a number of these for the same concern
