How do you unplug the orifice tube on auto ac?

To unplug the orifice tube on an auto AC system, first, locate the orifice tube, which is typically found in the liquid line between the condenser and the evaporator. Use a wrench to loosen any fittings and carefully remove the tube. If it's clogged, you can use compressed air to blow out any debris or use a solvent designed for cleaning AC components, ensuring all parts are dry before reassembly. Always wear safety gear and consult your vehicle's service manual for specific instructions.
