auxiliary coolant pump 07 mariner hv
 
My vehicle in ev mode within about two minutes produces no heat thru cabin vents, heat on full, car in ev mode. There is two electric coolant pumps, one is for power coverter and the other is a recuirculator for heater core. Where is the pump for heater core located?
