Here's what's involved, and the risks:
* Method 1 (Safer, but doesn't truly bypass): The safest way to "disable" the AC compressor is to simply turn off the AC using the in-cabin controls. This prevents the compressor clutch from engaging, so the compressor doesn't run. The system remains intact. This is the recommended approach if you are experiencing AC problems.
* Method 2 (Risky - NOT RECOMMENDED): Some people might try disconnecting the electrical connector to the AC compressor clutch. This prevents the clutch from engaging, thus disabling the compressor. However:
* High pressure: The AC system still contains refrigerant under high pressure. Disconnecting components while the system is pressurized can result in refrigerant escaping (harmful to the environment and potentially harmful to you), and damage to other components.
* System damage: Running the engine with the compressor clutch disabled can cause problems down the line depending on the exact cause of your problem. The system's pressure might rise too high, damaging components.
Instead of bypassing, troubleshoot the problem. If your AC isn't working, bypassing the compressor is treating the symptom, not the cause. Possible problems include:
* Low refrigerant: The system needs to be recharged by a qualified technician.
* Compressor failure: The compressor might need to be replaced.
* Electrical issues: A problem with the compressor clutch, relay, or wiring could be at fault.
* Other component failure: The condenser, evaporator, or expansion valve could be malfunctioning.
In short: Don't bypass the compressor. If your AC is not working, take your vehicle to a qualified automotive air conditioning specialist for diagnosis and repair. Attempting to bypass it yourself is dangerous and likely to cause more problems and expense in the long run.
