I just changed my air condition system

Winter doesn't matter, because tires are always measured cold.

A GM Chevy GEO tracker is Suzuki Vitara.
not told by you he problem or where it he drive-train or brake system ???? please name a problem.
no engine told. my guess v6. H25 , nor transmissions.
1.6 L L01 I4 (G16B Suzuki actual)
2.0 L J20A I4 130 hp
2.5 L H25A V6 155 hp
the word Orifice is mostly told in the contexts of these subjects below.
1: engine head, orifice to limit cam gallery feed oil to cam.
2: AC air conditioning HVAC expansion valve ,as a spray orifice inside.
3: brake ABS modulators.
4: A/T automatic transmission has many. (vast)
5: fuel injectors are kind of modulated ORIFICE
6: crankshaft gallery feed orifices.
surely more can be found, but no clue me the problem.

I have the full set of manuals and endless data on some like G16 engines. just ask,
and all 3 + transmissions.

Here's a video showing you where the fuse is. Check Engine Light Code P0410 Secondary Air Injection System Chevy Blazer...

best advice is the method i would use to located the orifice tube in the 2000 chevy venture. check the automotive repair book section in your local library. Most libraries have repair manuals on their automotive shelf section. find the a/c manual for your year and model car. make a copy of the page that has the information you need. you will need to make a copy because the library will not let those manuals be checked out. you might want to google for the location of the orifice tube location. I hope this helps.

How do I remove the orifice tube without damaging my evaporator core

WHERE IS ORIFICE TUBE ON 1999 CHEVY TAHOE 5.7 LITER ENGINE.

Hi, Orifice tubes are located in the high pressure line where it goes into the evaporator (close to firewall) or the condenser ( close to radiator) or in the line itself. I believe in my jimmy (about the same as a blazer) it was near the firewall where the high pressure line unscrews. Unscrew the line (think its a large coupler) and it should be inside there. Clean the cavity of any dirt or debris well and note the direction of the old orifice for installation.
Please rate this answer......Thanks! Mike

The orifice tube restricts the flow of refrigerant to the evaporator. This restriction allows high pressure liquid freon to change into low pressure freon before entering the evaporator. The orifice tube is located inside the hose running between the condenser and the evaporator. You'll need an orifice tube removal kit if you are looking to remove it.

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.

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 :
