OK,
This is what is going on.. I have no heat and dont know much regarding the heater core, or how the heating system works... This is my ideas, I know there is a heater core, Two hoses that go into this core, and somehow they are attached to the blower motor and the radiator.....
Now that you see im totally clueless this is the other observations I have made.
When I allow the Van to run for a bit, One of the hoses going to the heater core gets hot while the other does not., When I turn my heater on, the flow from my vents drops... When it is on vent it blows real nice, when it is on heater it is rather weak, same for the defrost...
And do I have to drain the Radiator to do anything with the core? Do I have to go through the glove box to access it?
Other information they may be relavent... its an 1987 Aerostar V6 3.0 has Air conditioning that does not work, I figured it was just out of freon but never really matered much to me anyway.
any observations you could give me would be greatly appreciated. Oh, And I have recently changed the thermostat.
