The heater core in a 2005 Cadillac CTS is located inside the vehicle, typically behind the dashboard on the passenger side. To access it, you'll often need to remove the dashboard and other components, as it is integrated into the vehicle's heating and cooling system. If you're experiencing issues with heating or coolant leaks, it may require significant disassembly to reach and replace the heater core.
