The last vehicle that I had that had an off on the heater control was a1978 Bronco,no AC. I had the same confusion and frustration with my 92 chev 4x4. I think it has to do with AC wether you have it or not. If it is on high always you may have a control rod disconected on heater core that bypasses the coolant as needed. This is generaly located up and under the jockey box. If the heater control has no resistance, I would look there
