On my '93 ford escort 1.9L, it is located under the dash, behind the heater control assembly.
You have to connect the both hoses that go into the heater core on the passenger side but that will throw codes and you will have a light on the dash
there would be 2 heater hoses that go into the firewall of your car. disconect these and join both together with a peice of tube and couple of hose clamps. this will bypass the heater core

It is cheaper to replace the heater core than it is repair it
The heater core is behind your dash inside of the ventilation ducts.
Drain the water from the cooling system. Remove the heater core hose. Remove the retaining bolts. The heater core will come out. Reverse the process to install the new heater core.
YES!! you can bypass the heater core. I just did this yesterday when my 93 Buick overheated because of a bad thermostat and broke the hose from the heater core. Follow the Big hose leading out from the right side of the radiator. It will lead to where the thermostat is then keep following along the hose that is connected to that and the hose will go behind the metal, inside of the car. Cut this hose right before it goes behind the metal and cut the one right next to it on the left and connect them together. That's it.
Could have a clogged line feeding the heater core. Disconnect return hoses from the heater core and verify coolant is flowing through the core.
you likely have a leaking heater core. Is this on the inside of the vehicle? if so then it defintately is a leaking heater core
Replacement of the heater core on a 1993 Mazda Protege is going to first require the removal of the entire dashboard. Once that is removed then the heater control box will need to be removed and disassembled in order to get access to the heater core inside.
