FEEL BOTH HEATER HOSES AS THEY ENTER THE FIREWALL TO THE HEATER CORE----INSURE THE VEHICLE IS UP TO OPERATING TEMPERATURE----AY THE SAME TIME, WHEN NO HEAT IS BLOWING OUT OF THE HEATER

HOW HOT ARE THEY? (CAN'T COMFORTABLY HANG ONTO ONE---BARELY WARM---COOL)

ONE HOT--ONE NOT?

REACH OVER AND FEEL THE UPPER RADIATOR HOSE......IS IT HOT?

WATCH OUT FOR THOSE PESKY MOVING ENGINE PARTS!

this with engine temp from mid to 3/4 on gauge.top hose very hot could not wrap hand around and hold .bottom hose cold.these 2 hoses seem to be connected with a double fitting with screw on top.I think poss. a bleed screw.the hot hose feels not hard but not easy to squeeze.if it dint get hot at both sides of the fitting I would think it could be blocked.do you need a image.

hope this helps bill Burke
