Your ac system has actuated doors control the temperature. Your right side temp actuator has failed. As you can see n this picture from the factory manual. That is called your hvac box or ip carrier. It's under the passenger side of your dash behind the glove box. Number 4 is the air temperature actuator for the right(passenger side) that's your faulty component. Unfortunately it's on top of the hvac box and the only way to access it seems to be by removing the dash and is a lengthy repair.

However, I can provide some general information about the air conditioning (AC) system in a 2015 Chevy Impala LTZ V6. In most modern vehicles, the AC system consists of several components, including the compressor, condenser, evaporator, and various refrigerant lines and hoses. There is no specific component called the "AC orphan tube" in standard automotive terminology. If you're experiencing an issue with your AC system and suspect a problem with a particular tube or hose, I would recommend consulting the owner's manual for your 2015 Chevy Impala LTZ, which may have information on the AC system components and their locations. Additionally, if you're not familiar with automotive repairs, it's advisable to consult a qualified mechanic or technician who can diagnose and address any AC-related problems in your vehicle. They will have the necessary tools and knowledge to locate and repair any issues with your AC system.

In a 1994 Chevy K1500, the compressor should receive power when the AC button is turned on, assuming that the system is adequately pressurized and there are no other issues preventing it from engaging. Here are some steps to diagnose the issue:

1. Check Refrigerant Levels: Low refrigerant levels can prevent the AC compressor from engaging. If your system is low on refrigerant, it may need to be recharged. This is typically a job for a qualified technician.
2. Check for Refrigerant Leaks: If your system is low on refrigerant, it's essential to check for leaks. A leak can cause the refrigerant to escape and prevent the compressor from engaging. Look for signs of oil or refrigerant leaks around the AC components.
3. Fuse and Relay Inspection: Ensure that the AC system's fuse and relay are functioning correctly. You can consult your vehicle's owner's manual or a fuse box diagram to locate the relevant fuses and relays. Replace any blown fuses or faulty relays.
4. Check the Pressure Switch: Many vehicles have a high-pressure and low-pressure switch in the AC system. These switches monitor the pressure in the system and can prevent the compressor from engaging if the pressure is too high or too low. Check these switches for proper operation and continuity.
5. Inspect Wiring and Connectors: Examine the wiring and connectors leading to the AC compressor. Look for damaged wires, loose connections, or corrosion. Ensure that there is no damage to the wiring harness.
6. AC Clutch and Compressor: If all the electrical components are working correctly, you may need to inspect the AC clutch and compressor itself. The AC clutch should engage and disengage when the AC is turned on and off. If the clutch isn't engaging, it may be faulty, or there could be an issue with the compressor itself.
7. Refrigerant Pressure Sensors: Some vehicles are equipped with refrigerant pressure sensors that can prevent the compressor from engaging if the pressure is out of the specified range. Check if your vehicle has such sensors and test them if necessary.
8. Professional Diagnosis: If you've checked all of the above and cannot identify the issue, or if you're uncomfortable working on AC systems, it's recommended to consult a qualified automotive technician or AC specialist for a thorough diagnosis and repair.

Remember to prioritize safety when working on your vehicle's AC system, as it involves high-pressure refrigerant and electrical components. If you're not experienced in automotive AC repairs, it's best to seek professional assistance to avoid injury or damage to your vehicle.
