I have a up defroster and down floor adjusdment on my heater box. I also have a small swithch on the lower dash under the headlight switch. It is not connected but leads to the heater. I thinking it controls the fan. Was there an adjustment for temp? I would like to get it going again just trying to figure how it was set up and how do I tell the difference.
