It is lots of fun to replace. The dash panel needs to be removed to access the heater plenum,(heater box). The AC has to be discharged prior to removing the plenum and then recharged when the heater core has been replaced. Once the AC system is opened to atmosphere it will absorb moisture from the air, so the drier for the AC system will also need to be replaced. If you have EATC, then you might want to upgrade the plenum, because the temperature blend door on these models tended to break.
