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.
on a 1999 gmc 1500 suburban 5.7 l where is the ac condensor
r134
I have 1998 chev suburban with rear air do they use two orifice tubes
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).
its an expansion valve and it is located in the black box ( in the rear unit)
If I change the AC compressor in a car, do I have to change the orifice?
It does not have an orifice tube.
Main line going into the avaporator canister! Passenger side! is it on fire wall
Most GM trucks/SUV's put their orfice tube on the outlet side of the condenser, right below/in front of the radiator.
How do you replace a starter in a 1999 suburban
It is designed to cycle the a/c compressure on and off to keep it from locking up during the winter months from not using it.
