No Heat
 

I've searched and searched and only found threads on people not knowing the dash vents are designed not to blow much/any heat and people with block weld in their heater cores.

My HVAC temp knob simply does not work.

(Story)
I've never had much in the way of heat in the car since I bought it and never knew why until last winter. I had no heat and I sat in the garage with the car off but in the on position and noticed the little noises associated with all the HVAC controls besides my temp knob... I messed with it for a while, finally heard a noise, and I had pretty decent heat after that. Then summer came around and I messed with it and got it back off again for the summer. Now I got nothing... No noise, no heat I froze my ass off twice frantically trying to get the knob to do something with the car fully warmed up and I don't want to have to lose out on the nice (non snowy/rainy) winter days until next summer because I can't get my heat to work...
(/Story)

What does the knob actuate?
Is there a connector I can jumper/test?
Is there something I can move mechanically?
Is there a fix for this?

At this point I don't care how inconvenient it is to do I just want to be able to have heat in the winter and no heat in the summer.

Thanks,

The anchor (a screw IIRC) for the mechanism can come loose and cause you to not be able to adjust. Pull the knob off (I don't remember if it just pulls off or has a locking set-screw) so you can see the fastener behind it, and it will be obvious what you need to do.
