2000 Dodge Dakota 3.9 V6. New water pump, thermostat, radiator cap, flushed the system. No leaks inside from heater core. Switch and blower motor functional, still NO HEAT! I've heard when you flush the cooling system on any vehicle, it does not properly flush out the heater core. You have to "reverse flush" the core. I have info on how to do this, just wondering if there is anything else I may have missed first.
