Then you're in luck! The cab air is an aftermarket system that uses a York compressor and all (fairly) common balance of system components. The first thing to check is the freon level, then the compressor clutch, then the rest of the stuff. Best to take it to a competent auto AC shop and have them diagnose it for you. Thing is that these systems are charged with the old, bad, freon (R-12) that isn't available any longer so you'd be better off to have the system purged and recharged with the newer non Earth-destroying variety of 134-a stuff. It's worth it. If there are any other problem areas the Ac shop can find and fix them with minimum drama. |

Worked out real well for me. These old system just leak over time but they work great. The only real issue (in my opinion) is that there's no electric fan to help keep the engine cooled down in slow traffic. If there weren't already several layers of coolers stacked in front of the radiator I'd have done it long ago. |

Yes, the cab air compressor is a York. Very common add-on A/C system back then. Have you taken it to an automotive A/C shop? I don't have any experience with fixing them so not sure how easy it is to get parts. |

Yep. I doubt that any of the RV companies bought the cab and chassis units with a factory AC system. At least I've never seen one. Ours do have a pretty standard York compressor and I believe that the AC system was supplied by the same guys who built the over-cab 120 volt system: Frigiking. I picked out a specific compressor for mine but I have to find out where I hid the info. |

Found it. It's a model R210R. The one I found is an ebay item from the midwest and comes with rebuilt compressor, clutch and oil for under $150.00. I looked at all the (Chinese) new ones and rebuilding my clutch but life's too short to remove and do it all over again in 6 months. If you know what I mean. Better a good rebuilt than a crappy new one. |

I would have thought that Hall would have since they were going for a premium build. I guess the price difference between the factory air and the add on was enough for them to save a few bucks. The factory setup is so much cleaner of an install. I was thinking about changing to a later model radial compressor if I ever decided to hook up the A/C. On my '79 Brougham, it had the same add-on system but I removed all compressor parts and brackets when I rebuilt the motor to make it easier to service. |

Nick, have you researched the correct conversion kit for this? The pulley allignment seems like a challenge but I'd love to change over mine is it isn't too much of a hassle. |

I was just going to get a setup from a later van in the junkyard, brackets, compressor, pulleys, etc. Maybe use a factory early condenser as well. One of those things I never got around to. Could convert it over to R134 at the same time. |

Getting one from a donor sounds like a LOT of difficult worked to me, and then what if it's also bad? Those compressors are really shoehorned in there behind stuff that probably won't want to come out and has nothing but sharp edges. You can get a rebuilt York with the clutch pretty reasonably and everything lines up. No? |

The later vans are so much easier to work on with the larger engine compartment and hood access. I haven't looked up replacement York compressors. Keep in mind that I was talking about doing this on my '79 where I already removed the compressor and all brackets that it mounted to and changed to standard pulley setup. If it was my GTC, I would just stick with what I have since it's all there. |

Yep. That's what I think I'll do. |
