The heater core on a 1993 Dodge Intrepid is responsible for providing the passenger cabin with heat. Some of the coolant from the radiator is redirected from the radiator system to the heater core in the cabin. The core acts as a heat sink, absorbing the heat from the coolant. A fan then blows this heat into the cabin. When the heater core fails, you won’t be able to get any hot air in the cabin. The only real solution is to remove the heater core so that you can get a new one in there.

Remove Heater Core
Disconnect the negative battery cable. Turn the retaining nut on the cable clamp counterclockwise and slide the clamp off the negative battery terminal. Slide a catch pan under the Intrepid’s radiator and remove the hose clamp on the drain hose on the bottom of the radiator. You should be able to reach the drain hose from the top of the engine. Turn the retaining screw on the hose clamp counterclockwise to loosen, then slide the clamp out of the way. Pull the hose off the radiator and drain the fluid into the catch pan. Pull the hoses off the firewall connection.
Loosen the hose clamps on the radiator to firewall connections and slide them out of the way. Pull the hoses off the firewall. Remove the Intrepid’s coin tray. Pull it straight out and remove the screw behind the tray. Open the glove box and pull it down so that it is all the way open. Lift up on the hinges and pull up on the entire assembly to remove it. Remove the four heater core cover screws. The heater core is in the passenger foot well behind the glove box. Remove the bolts holding the heater core to the firewall and slide the heater core off the firewall.
