THIS MAY SOUND KIND OF DUMB GOING OFF HOW THE WATER PUMP WORKS, BUT DOES ANYONE KNOW IF IT IS POSSIBLE FOR THE PUMP TO STOP PUMPING FLUID THROUGH THE MOTOR WITHOUT CAUSING ANY OTHER PROBLEMS. I AM ASKING CAUSE THIER IS CURRENTLY NO HEAT IN THE CAR. IT JUST SEEMS THAT THIER IS NO FLUID PUMPING THROUGH THE CAR.
