Heating core is plugged not allowing enough air thru

[point_man8]

Either the blend door is leaking/not closing fully against the cold air inlet, or the core is plugged not allowing enough air thru it.

any idea how to fix either of these

Point-------
After the engine is fully warm,feel both heater hoses.If both are hot and feel about the same heater core is usually not the fault.

You could try flushing the heater core.

If your cooling system is open to the air, your coolant won't heat up enough to do much good. I suggest that you test your cooling system along with your rad cap. It happens alot on our military vehicles.

Your director / control doors could be stuck. It's been known to happen. Crawl underneath there, get a good luck, and make sure that when you turn the knob the director doors actually move (not sure if you can see them on your vehicle)

make sure the fan is working right
when they start going they slow dowm and dont put the volume of air over the core like when they were new
