Need an air conditioning diagram of 1997 Chevy Lumina for location of orfice tube placement.

If you look at the low pressure side line going from the dryer to the condenser you will find a crimped place and it is probably down by the condenser and that is where the orifice tube is.

All hoses were removed and we could not find the orifice tube. where is this located and can u show me a diagram

The orfice tube for the AC is generally located inside the aluminum line at the front of the engine and must be pulled out with a small hook tool or needle nose pliars. As far as the diagram and specifics go, you will need to provide some details about your vehicle before you can get some exact help.

Hello chericegodea: My name is Rpger and I will help you. The orfice tube is located in the liquid len at the evaporater coce. This will be the small diametor linn at the firewall. Seperate the fittings at the firewall and look inside the tube that comes through the firewall. The object you see will be the orfice tube. Make sure the A/C has been recoverd or that the system has no pressure as there could be a dangerousexscape og freon and gas. Should you need further help please just ask. Please rate the answer. Thank You for using FixYa. Roger

Replacing Accumulator in 1993 GMC Diesel 6.5. Having a hard time figuring out where to put the Orifice tube.

the orfice tube goes in the high pressure line, that is the small line near the accumulator, disconnect that line and the orfice is in the accumulator inlet tube, u may need an extra long nosed needle nose pliers to extract it.
