Remove the glove box and the bottom part of the black plastic box that houses the heater core. Outside, you will need to remove the hoses from the heater core tubes that protrude through the firewall. Hard to do without a very expensive special tool. The best way, if you're sure the heater core is gone, is to cut the tubes just on the outside of the firewall or just inside whichever gives you best access.

The hoses are connected to the heater with special clips which makes connection easy but disconnection almost impossible. When removing hoses make sure to mark the hoses (which goes on top) for proper replacement. be sure to use new plastic inserts available at the dealer. Use a little Vaseline or liquid soap to lubricate the rubber rings so as not to damage them and allow them to slip on easily.

Cutting the heater tubes will save you a bundle in not buying the special tool.

Heater core is located inside the H/AC "suitcase". It can be a chore, but you're best bet is to remove the 'suitcase' and remove the heater core once the suitcase is on the ground.
