Same post again? Look at two AC pipes entering heater box. One is low side (large) and one is high side (smaller). Disconnect the high side pipe union and inside the pie going into heater box is the orifice tube.

Where is the inline air conditioner filter located

What you are referencing is probably the orifice tube + a screen.
There are many things that can change the air temperature inside the car.
1. Inside AC/HEATER duct under the dash, the temperature door can be open a bit and let the warm air mix with cold air temperature.
2.The purpose of the orifice tube, that is between the high pressure and low-pressure tube you can feel with your hands the cold and warm tube
The screen is blocking particles of metal from A/C compressor if the compressor is defect.

high-pressure side is HOT
low-pressure side is COLD
3. A/C compressor clutch could slip more than it should. The air gap has too much clearance.
The location of the orifice tube is :

Where exactly is the orifice tube located at on a 1996 (DOHC v6)?

it's in the high pressure liquid line.

A/C Evaporator Core Orifice The A/C evaporator core orifice (19D990) should be replaced whenever the A/C compressor (19703) is replaced for lack of performance (internal damage). The A/C evaporator core orifice, located in the condenser to evaporator tube (19835), cannot be serviced in detail as a component of the line. If replacement is necessary, follow the procedure outlined for Liquid Line Removal and Installation. An orifice tube replacement service kit may be used as an optional service procedure. Refer to Section 12-00 for information regarding the use of an A/C Evaporator Core Orifice Replacement Kit E5VY-19D695-A.
-----------------------------------------------------------------------------------
A/C Evaporator Core Orifice Replacement Kit Installation
  1. Discharge A/C refrigerant system. Refer to System Discharging and Recovery as outlined.
  1. Remove condenser to evaporator tube (19835) from vehicle.
  1. Locate A/C evaporator core orifice (19D990) by three indentations or a circular recess in metal portion of the condenser to evaporator tube.

  1. Note angular position of ends of condenser to evaporator tube so that it can be reassembled in correct position.
  1. Cut a 63.5 mm (2.5 inch) section from condenser to evaporator tube at A/C evaporator core orifice location. Do not cut closer than 25.4 mm (1 inch) from start of a bend in tube.

  1. Remove contaminants from the two pieces of the condenser to evaporator tube.
  1. NOTE: The inlet half of the condenser to evaporator tube will be positioned against the A/C evaporator core orifice tabs when correctly assembled.

    Lubricate fitting with clean refrigerant oil and assemble orifice tube kit (with A/C evaporator core orifice installed) to condenser to evaporator tube. Make sure flow direction arrow is pointing toward evaporator end of the condenser to evaporator tube, and taper of each compressor ring is toward compression nut.
