how do you get to ac orifice to replace?

Orfice tube Removal NOTE: Installation of a new suction accumulator is not required when repairing the air conditioning system, except when there is physical evidence of system contamination from a failed A/C compressor or damage to the suction accumulator. Recover the refrigerant. Remove the wiper arm and pivot shaft. Remove the nuts and the fresh air inlet duct. Disconnect the condenser-to-evaporator line fitting at the evaporator core. Discard the O-ring seals. Disconnect the evaporator core orifice fitting and remove the evaporator end of the condenser-to-evaporator line. Discard the O-ring seal. Inspect the evaporator core orifice for damage before attempting to remove it from the line. If the evaporator core orifice is intact, engage the special tool. Hold the T-handle stationary while rotating the tool body to remove the evaporator core orifice. If the evaporator core orifice is broken, screw the end of the special tool into the broken orifice. Hold the T-handle stationary while rotating the tool body to remove the evaporator core orifice. Installation Lubricate the evaporator core orifice O-rings in clean PAG oil and install the evaporator core orifice using the special tool. Install the evaporator end of the condenser-to-evaporator line and connect the evaporator core orifice fitting. Install new O-ring seals. Connect the condenser-to-evaporator line fitting at the evaporator core. Install new O-ring seals. Install the fresh air inlet duct. Install the wiper arm and pivot shaft. Lubricate the refrigerant system with the correct amount of clean PAG oil. Evacuate, leak test and charge the refrigerant system.
