I have 1998 chev suburban with rear air do they use two orifice tubes
This orifice tube is by what they call the condenser, usually found by the core support
Most orifice tubes are placed in the high pressure line to the evaporator at the fire wall connection. You will have to empty the freon from the system to replace the orifice tube which is not very expensive (the tube, that is).
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.
Most GM trucks/SUV's put their orfice tube on the outlet side of the condenser, right below/in front of the radiator.
On some suburbans its at the connection behind passenger turn signal.
Located in front of the radiator on the passenger side in the condensor line.
Should be on the front passenger side next to the radiator.
Orifice tube on f150 with 4.2
It does not have an orifice tube.
I had trouble finding the orifice tube in my Ranger too. After taking off all connections, I finally found the orifice in the bottom tube coming off the condenser. You can not tell by looking at the line from the outside. Once you loose the nut and pull the tubes apart you will see the end of the orifice. I had trouble finding the orifice tube in my Ranger too.

It uses an expansion valve, not an orifice tube.
