I can't turn down the heater,,, I turn the **** all the way to cool and still blasts the heat,, even turning on the AC on high,, still heat. Is the temp control electronic or vacuum line controlled? I looked in my Haynes manual and found nothing about the controls except how to pull them out of the dash. If there have been previous threads on this,,, direct me to them please,

 

Good to see someone else from Rapid City...
