On some suburbans its at the connection behind passenger turn signal.
where is the orifice tube location on a 1996 GMC pickup truck 1500
The orifice tube on a 1997 GMC Suburban is located in the high-pressure line of the air conditioning system, specifically inside the liquid line. To access it, you typically need to locate the liquid line running from the condenser to the evaporator, and the orifice tube is usually situated near the evaporator inlet. It may require some disassembly of components to reach it properly for replacement or inspection.
The rear orifice tube on a 1997 GMC Suburban is located in the HVAC system, specifically in the line that connects the evaporator to the accumulator. To access it, you typically need to remove the rear A/C evaporator assembly, which may involve disassembling some interior panels. Ensure you follow proper safety procedures and refer to a repair manual for detailed instructions.
Many GM vehicles put the AC orifice tube right after the condenser coil. It would typically be near the bottom, almost connected to the condenser. My '99 Suburban AC orifice is located in the line that runs across the passenger side inner-fender. There is a union very close to the innermost edge of the battery tray. Break that union (after relieving pressure) and you will find it there.
Suburban
The 1999 GMC Suburban typically has one A/C orifice tube located in the liquid line between the condenser and the evaporator. However, some configurations may have two tubes if the vehicle is equipped with dual-zone climate control systems. It's important to refer to the specific service manual for your vehicle's configuration to confirm the exact setup.
It's located on the left side fender well right before you get to the battery, look down and you will see a a/c line disconnect that line and it will be inside, you will needle nose pliers to pull the orifice tube out. >>> (your a/c system has to free of all pressure before you disconnect that line!!!!!)
The orifice tube on a 2003 GMC Envoy is located in the liquid line of the air conditioning system. To access it, you'll typically need to follow the line from the condenser to the evaporator. It is often found near the firewall, between the condenser and the accumulator. Ensure the vehicle's AC system is depressurized before attempting to locate or replace the orifice tube.
at the evaporator in front of the radiator where the line compression fits together
