What you *can* do is effectively disable the AC by doing the following:
* Turn the AC off: This is the simplest solution. The system won't operate unless the AC button is engaged.
* Disconnect the AC clutch: This prevents the compressor from engaging. This requires locating the AC clutch (it's electromagnetic and usually on the compressor) and disconnecting the electrical connector. This is the safest method of temporarily disabling the compressor *but still leaves refrigerant in the system*. Do not attempt this unless you are comfortable working with car electrical systems.
* Replace the AC clutch relay with a bypassed one: This permanently disables the AC clutch. This is more involved than disconnecting the connector, requiring finding the relay and bypassing it. This requires knowledge of your car's electrical system.
Important Considerations:
* Refrigerant: The AC system contains refrigerant. Discharging it is environmentally damaging and illegal in most places. A professional AC shop must handle the refrigerant properly.
* Safety: Working with the AC system and electrical components requires caution. Improperly disconnecting components could lead to damage or injury.
* Belt Damage: Running the serpentine belt without the AC compressor load might seem to reduce belt wear but can also potentially put increased strain on other components, shortening their lifespan.
If your air conditioning is simply not working, diagnosing and repairing it is usually more cost-effective and environmentally friendly than trying to bypass it entirely. A failing compressor, a leak in the system, or a faulty electrical component are more likely culprits than a system needing "bypassing". Consider seeking professional help from an automotive mechanic to determine the issue and have it addressed safely.
