Ok, I have an 03 Evo. Nothing special. The problem I have is that just a few days ago my heater nob on my dash started getting sticky right between the cold and hot sides, right at twelve o'clock. Anyway, I tried to turn it and it wouldn't budge. I basically just turned it good and hard and it went. But i heard a noise in the dash and now i don't have any heat. I basically get luke-warm air that comes out. its december in south dakota and i am freezing my balls off. Any suggestions? All are welcome.
