I believe the orifice tube on this model requires the a/c pipe to be cut to install a new tube. You need to discharge the system, replace the tube, then evacuate miosture with a vacuum pump, then recharge with R134A refirgerant. Not a job for a non technical person.

The oriifce is in the line just before the evaporator that is in your car a/c heater case. It is where the liquid refrigerant turns into a vapor as it comes out of the orifice and then it absorbs heat from the air going into you car, thus blowing cold air. Moisutre in the warm air condenses and as he iar gets cold and it drains out of your evaporator and out the drain & onto the ground

There is one orifice tube for the font air. It is located in the a/c line coming from the condenser to the evap. core. the rear a/c has and expansion valve attached to the rear evap. core. Hope this helps.

SOURCE: Where is the orifice tube located in the a/c

The orifice tube should be located inside of the metal AC line from the condenser. The discharge hose (from the compressor) connects to the top on the condenser (inlet). The orifice tube mounts in the bottom of the condenser (outlet to the evaporator). The outlet tube of the condenser has a 45º upward angle. If it is not in that location it will be farther out on the same line where it connects. Here is a diagram that might help.

Were is expansion valve in a 2002 Chevy trailblazer in the truck


Are your asking about TXV valve thermal expansion valve for A/C system ? If you are ,yours doesn't have one . Has an orifice tube , The orifice tube is located in the liquid line between the condenser and the evaporator !
The orifice tube is the dividing point for the high and the low pressure sides of the A/C system. As the refrigerant passes through the orifice tube, the pressure on the refrigerant is lowered. Due to the pressure differential on the liquid refrigerant, the refrigerant will begin to vaporize at the orifice tube. The orifice tube also meters the amount of liquid refrigerant that can flow into the evaporator.
Unless you are referring to the auxiliary A/C system for the back of the vehicle , it uses a
The rear TXV is located at the rear evaporator inlet. The TXV is the dividing point for the high and the low pressure sides of the rear A/C system. As the refrigerant passes through the TXV, the pressure on the refrigerant is lowered. Due to the pressure differential on the liquid refrigerant, the refrigerant will begin to boil at the expansion device. The TXV also meters the amount of liquid refrigerant that can flow into the evaporator.

It is located inside the condensor tube running to the evaporator.

Here are the removal/installation instructions as per alldata:

TOOLS REQUIRED

J 39400-A Halogen Leak Detector
J 26549-E Orifice Tube Remover

REMOVAL PROCEDURE
-Recover the refrigerant. Refer to Refrigerant Recovery and Recharging.
-Remove the air cleaner assembly.
-Remove the vacuum brake booster.
-Remove the condenser tube.
-Use J 26549-E in order to remove the expansion orifice tube. IMPORTANT: DO NOT use any solvents or chemicals to clean the porous plastic inlet filter of the expansion orifice tube.
-Inspect the expansion orifice tube for the following conditions and clean or replace with a new tube as indicated:
-Broken plastic frame (1); replace the tube.
Inlet filter (3) damaged or plugged with fine gritty material; replace the tube.
Inlet filter (3) coated with metal chips, flakes, or slivers; remove the coating with low pressure shop air ONLY and reuse if the filter is cleaned satisfactorily. Do NOT reuse the O-ring seals (2).

INSTALLATION PROCEDURE

IMPORTANT: Lubricate the new O-ring seals (2) with mineral base 525 viscosity refrigerant oil.
If you reuse the orifice tube, install new O-ring seals (2).
Carefully grasp the edge of the expansion orifice tube (1) without touching the inlet filter (3) and insert the expansion tube into the condenser tube until fully seated.
-Install the condenser tube.
-Install the vacuum brake booster.
-Install the air cleaner assembly.
-Evacuate and recharge the A/C system. Refer to Refrigerant Recovery and Recharging.
-Leak test the fittings of the component using J 39400-A.
