1992 GMC C2500 no heat out of heater
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.
