Water will pass through both front and back heater cores. Are these cores one continuous tube or some other design with some type of bypass if the small tubes are still obstructed? Hot air will come out of the vents when you first turn on the heater but temperature of air will cool quickly and extremely fast if you have the fan on high. Doesn't make sense.
have the same problem?
