Where is the heater core on a 1996 Isuzu trooper?

The heater core on a 1996 Isuzu Trooper is located inside the vehicle, behind the dashboard, typically on the passenger side. To access it, you'll need to remove the dashboard and possibly the center console, as it's housed within the heating and ventilation unit. It's important to ensure the vehicle is properly cooled down and disconnected from the battery before attempting any repairs.
