Ok so my knobby thing broke to change the temp in my car during the summer. It was on Cold so I havent really worried about it. Well now in the cold mornings I would like to turn the heat on but my knob is stuck on cold...

So I am looking for the temp knob if anyone has a spare lying around I have tried to take the one that controls how hard the air blows out but it really doesnt budge and I really dont want to break that one either. Let me know what you got!
