Re: A/C Compressor Clutch

I'm not clear on whether the compressor seized and caused the clutch failure, or if this is simply an AC clutch issue. Can the compressor itself be turned with a wrench? If only a pulley bearing, maybe a replacement bearing can be obtained and installed. Typically, buying an AC clutch is comparable ...

Re: AC stops working when I rev the engine (live data video)

Your computerized stuff is interesting, but first ensure that the AC clutch is not disengaging when you rev.

Re: 2006 Saturn Vue cooling at idle

Over the last 2 years the A/C would cool fine going down the road and immediately stop cooling at a stop. What am I missing? To me, this seems to align with a failure to cool the condenser properly; so I'd make sure all the fans are operational whenever the AC is running. Also make sure that the fa...

Might need NEW Sanden SD708 Model 7225 compressor

I might need a NEW Sanden SD708 Model 7225 compressor or other clone you have confidence in, not a remanufacture/rebuilt. I bought the current SD708 Model 7225 from you at Arizona Mobile Air at the Clarendon location October 2014, and it appears to have a leak in the compressor body seam, at the rea...

Re: Old R12 System

To update in case anyone wonders; I swapped out compressors and the system functions perfectly. Great !!! We like to hear the updates. Three weeks ago I removed a thin AC clutch shim to restore full operation of my 1998 Frontier AC clutch; I don't think that I posted anything when I had that interm...

Re: 2009 Honda Accord Intermittent AC Cooling

Check the compressor clutch gap. Bohica is wondering if the AC clutch is slipping, causing your intermittent cooling. Visually check to see if the center of the AC compressor is turning when this lack of cooling is observed. Two weeks ago I had similar issue on my 1998 Frontier - the AC clutch was ...

Re: AC stops working when I rev the engine (live data video)

Hello, I have Audi A6 from 2006. When I rev the engine past 2000 rpm the AC stops working. If I rev the engine again I hear a hissing sound and the AC starts working normally. I made a video with live data. As you can see from it, the gas pressure drops immediately after I rev the engine and the ev...

Re: 1979 Lincoln R12 System - Blows colder at idle

There are few shops in town that still work with R-12 systems, and the ones that do said that they can recover my refrigerant but that it cannot be re-used because it will be contaminated, so they will have to charge me for new refrigerant. Is this true? I'm under the impression that the recovery s...

Re: ac quit blowing cold suddenly

Good. Sounds like you have a small leak, and enough R134a leaked out over the 5 years to where you noticed lack of cooling. If the cooling loss occurs again sooner than that, then time to find the leak and repair it. NEVER ADD ANY SEALER OR REFRIGERANT CONTAINING SEALER !!! If the AC clutch is slipp...

Re: ac quit blowing cold suddenly

You state that the compressor is always engaged, good. I'd get real gauge set and measure both high and low refrigerant pressures at about 1800 rpm. Post those. No more adding R134a (never add any sealers or refrigerant containing sealer) blindly either. You had a leak a few years ago, that did not ...
