How do you replace the AC orifice tube on 1994 gmc Sonoma 2w 4.3 liter v6?

To replace the AC orifice tube on a 1994 GMC Sonoma with a 4.3-liter V6, first, ensure the AC system is fully discharged to avoid refrigerant exposure. Locate the orifice tube, which is typically found in the liquid line between the condenser and the evaporator; you may need to remove the line for access. Using a pair of pliers, carefully pull out the old orifice tube and insert the new one, ensuring it is seated properly. Reassemble the lines, recharge the AC system with refrigerant, and check for proper operation.
