Yes.
Should be a plug right at the compressor. Or just don't turn on your a.c. If it grinds when clutch is not engaged then unplugging won't help, you need to replace clutch. |

If it's grinding with the AC on, yea pull the plug, NBD
If it's grinding when the AC is off/ unplugged? You probably are going to have problems. IIRC since mustangs have stock AC, you might not be able to run a shorter belt like on some vehicles that had AC as an option. I would pick up a AC eliminator/ delete pulley kit if unplugging it doesn't work. I've had two compressors fail from the clutch/ bearing going out. The explorer was pretty spectacular with sparks shooting out of the wheel well and the AC compressor case glowing red and smoke everywhere. Even melted the serpentine belt. People with more experience can probably provide more info. |

Edit: looks like there's a "delete" pully which I can install but I think I'd have to remove the AC to do that and I want to keep the refrigerant inside. Looks like I'll just have to pretty much replace it I guess.  http://www.rockauto.com/catalog/moreinfo.php?pk=971229&cc=1354722 |

I'll look into the shorter belt. The problem with trying to run a "short" belt on your vintage is the location/design of the tensioner.

You can put a clutch coil and pulley assembly on that car with the compressor in place and the cooling fan removed.

That would be the ideal solution (new clutch kit), but I just don't know if there isn't already damage to the compressor (I'm ignorant there may not be but it would not surprise me if there is), and who knows how long the compressor will last anyway. I'm guessing the compressor is messed up to at this point. The grinding is bad and advice on other forums seems to indicate that the compressor most likely won't last much longer anyway so it's just best to swap them both out rather than just the clutch hence me thinking I need to just replace the whole thing. |

. Gonna call my mechanic guy and see how much he'll charge to swap out the AC compressor (if he can do it). Worse comes to worse I guess I'll have to drain the refrigerant and remove the AC compressor myself and install the pulley. That shouldn't be too hard I imagine. You can bring it in, have the system evacuated and then swap out the dryer and Compressor yourself. Then, you just go back in and have the system evacuated and filled again. |

Keep in mind for the warranty on most compressors you are required to replace the accumulator/drier and expansion valve/orifice tube so that may be an unforeseen cost to you. You might get away without it but you're inviting trouble due to the age of components and the life of the desiccants in the accumulator, moisture + r134 = hydrochloric acid, and the compressor oil is very hygroscopic.
