I'm just a chick who likes to work on cars
I'm doing some troubleshooting on my 2006 Buick Lucerne 3.8.
I can't seem to find the exact location of the orifice tube. Can one of you guys help me with that? Or gals..
Maybe with a picture would be Great!!

Is this for a Buick Lucerne 2006 or a LeSabre?
Does it even matter being that they are both Buick? 🤔

looked through my SI manual, and the Lucerne actually has a Thermal Expansion Valve (TXV) not a Fixed orifice Tube. replacing the TX Valve involves complete removal of the HVAC Module (the Plenum Box) from the car and removing the heater core from the HVAC module.
