So the temperature dial on my dash no longer changes the temperature of my HVAC system. I always had this little click when turning the dial and then one day something finally snapped. Can someone tell me a good place to order parts if i go in and try and fix it myself? I have a 2002 wrx.
(I really hate my dealership and really do not want to go through them, THEY CHARGE FOR QUOTES!!)

On an unrelated note i found all the service guides etc for my car on the internet if anyone needs a copy I can find a way to get it to you.
