Removing interior trim requires the use of special upholstery removal tools used to pry apart fastening clips without damaging them. Be sure to use these tools when removing interior components. Have the system discharged and the refrigerant recovered by an air conditioning technician. Disconnect the negative battery cable from the remote ground terminal or battery. Drain the cooling system. On the driver's side of the firewall, remove the uppermost nut that holds the heat shield. Remove the two nuts holding the heat shield to studs on the dash panel. The heat shield can then be rotated and tilted to aid in removal. Remove the bolt securing the refrigerant lines to the air conditioning evaporator. Disconnect the lines and remove the seals. Place towels underneath the heater core tube fittings. Remove the clamps and disconnect the heater hoses from the heater core. Remove the bolts holding the heating/air conditioning housing to the instrument panel. Remove the front sill trim on both the passenger's and driver's sides. Remove the front seats. If equipped, loosen fasteners and remove the passenger side amplifier. Remove the B pillar trim panels and cowl trim panel on the driver's side. Remove the center console. Pull back the carpet to expose the rear seat ducts. Remove the instrument panel. On 2015 and later models, the heater core/HVAC housing is removed as an assembly with the instrument panel. Once removed, the heater core can be separated from the panel by simply disengaging the wiring harness and removing the four mounting fasteners. Disconnect the shift interlock cable connected to the floor duct and move aside. Remove the screws holding the left front floor duct to the heating/air conditioning housing and remove the duct. Remove the air conditioner condensation tube. Remove the fasteners holding the left and right rear distribution ducts. Disconnect the ducts from the heating and air conditioning housing. Remove the nut holding the heater/air conditioner housing to the passenger's side dash panel. Pull the heater/air conditioning unit rearward. Remove the heating/air conditioning housing through the passenger compartment. Place the heater/air conditioning housing on a work bench. Remove the foam seal from the connection tube flange holding the heater core outlets. Un-clip the fasteners securing the flange and remove the flange from the heating/air conditioning housing. Remove the fasteners securing the retaining brackets. Remove the heater core line retaining brackets. Carefully remove the heater core from the heater/air conditioning housing. Installation is the reverse of removal.

Special custom-built tools are needed to take off trim inside cars made before 2014 without causing any harm to these clips. You will need to have these special removal tools with you while taking apart your vehicle's interior parts. Start by asking a professional to drain out the refrigerant and collect it from your air conditioning system. Separate the car's power from the remote battery anchor point. Drain the cooling system. Twist and lower the heat shield by removing a nut on top of the firewall on the driver's side. Then take off another two nuts that keep the shield attached to bolts on the dashboard. Untighten the bolt that holds the refrigerant lines to the evaporator of the air conditioner. Take off the lines, and extract the seals. Block line openings with plugs or tape to keep out moisture and dirt. Put towels under the tube fits. Remove clamps and disconnect heater hoses from the heater core. Plug or tape over openings to avoid spillage. Lift the heating/air conditioning housing from the instrument panel using the bolts, then peel off the front trim on both passenger and driver sides. Then, take out the front seats. When present, take out and offline the secondary amplifier is the passenger side. Pull out the side trim panels by the B pillar, next to the windshield. Also take off the trim panel directly above the driver's seat. First uncover the floor where the seats meet, then take out the dashboard. Take the shift interlock cable away from the floor duct and move it out of your way. Take out the screws that hold the air duct to the heating/air conditioner housing on the driver's side, and afterwards remove the duct and the tube that drains water from the air conditioner. Use pliers to get rid of the bolts that fasten the left and right back ducts to their housing over the heating and air conditioning system. Take out the dash panel passenger's side heater/air conditioning housing nut, then gently tug the heating system forward and pull it out through the passenger compartment, making sure towels cover the insides to catch any flowing fluids. On a workbench, pry the foam seal from the metal flange that holds the heater core tubes. Then unpin the metal flange from the heater/air conditioning housing and detach it. Untighten and take off the fasteners connected to both the heat core retaining brackets and the heater core line retaining brackets. After that, cautiously pull the heater core out from its place inside the housing. To install a new heater core, you replace the old seals where the fittings connect and fill the cooling system again. You'll need first to drain and flush the cooling system when putting in a fresh heater core.

Remove the heating/air conditioning housing through the passenger compartment. During removal of the heating/air conditioning housing, ensure that the interior of the car is properly covered with towels to catch any fluids that may come off the housing components. Place the heater/air conditioning housing on a clean working surface. Remove the foam seal from the connection tube flange holding the heater core outlets. Unclip the fasteners securing the flange and remove the flange from the heating/air conditioning housing. Remove the fasteners securing the retaining brackets. Remove the heater core line retaining brackets. Remove the heater core from the heater/air conditioning housing. Installation is the reverse of removal. Use new seals for the heater core fittings and refill the cooling system. If a new heater core is being installed, the cooling system must be flushed.
