Inherited a 2000 Ranger XLT 3.0l when my wife's sister passed, one of the very few items that my wife has to remember her by. We are taking steps in getting it mechanically sound before a paint job and interior redone. The front end has been redone with little left to do except the heater. Getting the heater to work properly has been 6 weekends of frustration and head scratching.
Heater core has been flushed and back flushed several times, , Heater control valve replaced, thermostat replaced, radiator flushed, Blend door checked for opening and closing. all of that in the first few weekends with little success. Note that the coolant was rusty colored. The HVAC only gets mild heat on the "fresh air position" but the air is hotter at the blend door. After all of that a week later the pretty new green coolant was back to a rust color. Also the Climate control module was replaced with a used OEM one. The original one had a 25a fuse stuck in it because it would blow the 7.5 that it's called for.
That led to the radiator being replaced, a full engine flush, new thermostat, new radiator cap and........ same result Mild heat on the the fresh air position only and nothing on any heat position. The only things that haven't been replaced are the 2 heater hoses running out of the heater core and the heater core itself.
