Re: [MBZ] OT: 1992 Suburban AC
Most likely a fuse or the control unit, but there may be a high pressure switch on that system, or a few other switches thrown on just to make a mess like most later GM ac systems that make me ill and angry to work on. Hard to say without seeing it. you may be able to find some decent online diagrams on autozones website Robert Jim Cathey wrote: My BiL brought his burbinator by for an AC recharge. Unfortunately that's not what's wrong with it. Surfing for an hour or two got me nothing on how it's constructed. The compressor wouldn't cut in, though the low side pressure was plenty high and the switch on the accumulator was closed. I jumped the compressor on to see what happened. The pipe to the condensor gets hot, pipe from gets warm. By the time that small line gets to the firewall it's ice cold. Accumulator itself is warm, the suction hose at the compressor is coolish. Unfortunately my gauge set wouldn't go on the high-side fitting, so I don't have that pressure. No idea why the compressor won't run either. Anybody got a quick checklist or a place to look for the same? He's leaving tomorrow AM, so I probably won't have time to do anything but who knows...

You sure the switch is good on the accumulator? That would be my guess --- Kaleb C.

Re: [MBZ] OT: 1992 Suburban AC
mess like most later GM ac systems that make me ill and angry Well, got zero satisfaction on that job, but the neighbor's GM thunder chicken came by today and got juiced. Unfortunately it was late in the day and not so hot, maybe 75, but the vent temps did drop to 38 degrees. And the gauge set fit on it, at least. I dropped by McParts to buy a Chilton's (or whatever) if it covered the 'burb, but the info therein was too rudimentary. I saw that a later year had two safety switches and a relay, another switch was added a year or two after that. But not worth $20 to have, and besides the vehicle has already left. -- Jim ___ http://www.okiebenz.com For new parts see official list sponsor: http://www.buymbparts.com/ For used parts email [EMAIL PROTECTED] To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
