Heater problem
1992 GMC C2500 V8 Four Wheel Drive Manual 150000 miles

There is poor circulation through the heater core, I have flushed the heater core, and there is good ciriculation when I have the garden hose hooked to it even with low pressure. But it won't circulate from the engine through the heater core, and there is good pressure coming out of the engine block to the heater core.
