2002 Dodge pickup heater just doesn't heat up the cab. I don't think it is the blend door (hot to cool knob). If you turn it on vent and hold your hand at the vent doors and turn the knob to cool it gets cool. If you turn it to hot is gets warmer. That leaves either the engine thermostat or a plugged core. The temperature gauge on the dash reads 1/2 way - which seems normal. Today I put a piece of card board in front of the radiator and it actually put out some heat. Not extremely hot but warmer. I subpose I covered at least 3/4 of it. Temperature gauge moved almost all the way to the red zone. Like I say warm air but not real hot in the cab. You would think it would get very hot and you would have to turn it down. Could be the core. Another thing I found is a "coolant bleeder" on the engine block. Engine is a 4.3 V8. Could there be somekind of an air lock? Plastic tank for cooling system is clear full. Any other ideas?
