    All, I have a 2007 Honda Odyssey. The AC stopped working so I hooked up a pressure gauge from one of the self charging kit with the engine off and the pressure was 100 pounds. I let out pressure and only air was coming out and sometimes it was warm air and at times it would be cool for a second or two. Got the pressure down to about 30 pounds.

    Started the van and ran the AC on high and pressure immediately jumped back up in the red zone within 20 to 30 seconds. Let some pressure out, and again only warm air came out. Does this mean I am sucking air from somewhere? What should I be checking? I don’t have a gauge to check the high pressure to see if it is normal or not.

    Ok, I now understand that with the engine off, I am reading static pressure. So, by it not changing when the vehicle is running and clutch engages, am I looking at a broken shaft on the compressor or something else?
