It is located in the high pressure line coming from the condenser. that is the smaller of the two lines and it is the lower one. its approximately 10 inches back. look for the indentations on the line near the fitting. they look almost like a crimp. they are there to stop the orifice tube.

Where is the orifice tube on my 2004 gmc envoy xl air conditioner system

Not sure specifically on that model but if you follow the line from the compressor to the condensor then out of the condensor to the evaporator it will be between the condensor and evaporator usually the tube is wraped in plastic but it could be in the heater box itself also if you have rear ac the rear unit uses a thermal expansion valve on the rear evaporator not an orifice tube. What is your concern thats leading you to find the orifice tube if your dont mind me asking

Where exactly is the orifice tube located on a 1993 GMC C1500 4.3L pick up truck.

In the bottom tube of the condenser core. Remove the grill and the tube that comes up at about 60 degrees on the condenser.
If you look closely at the tube you will see a small dimple about 4ins along from the connector. That dimple is what stops the orifice tube from traveling further down the condenser tube.

Where is the orifice tube on 99 gmc sonoma pickup

The AC orifice tube is located in one of the metal portions of your hoses. It may be identified by about a few inches from the nut you shall see four small indentations around the surface of the tube. This filter is located inside the tube and usually needs a special extractor to remove.

Good Luck

The orifice tube is located inside the liquid line where it connects to the condenser. This line is located on the passenger side of the car and has the low side charge port on it. this line unscrews right where the orifice tube is located... Hope this helps
