Does this have a center console?
If yes, the console has to be removed....the hush panel on the passenger side has to be removed.....clamp both heater core hoses to prevent loss of coolant.....remove clamps on end of hoses to the heater core....remove hoses from heater core tubes....remove right angle drain tube from the hvac drain on the firewall....
Moves seats as far back as possible.....pull carpet rearward.....there is a heater core panel secured with several 5.5mm screws....remove screws.....the panel fits in grooves ....you have to pull the panel down slightly to just clear the grooves, and then pull rearward....careful, if you don't pull down enough on the firewall end of the panel, you can crack or break that panel....that panel holds the condensate that goes out the drain tube....once removed, there is a metal fastener that has to be removed to pull down the core....
