RE: 1996 XJ^ VDP AC Expansion valve - 6/7/2008 7:34:24 AM    opastu   Posts: 2 Joined: 6/6/2008 Status: offline The problem I have is that the compressor shuts itself down very shortly after activating.  There is a full charge of freon.  Periodically, the compressor will stay on a bit longer, perhaps for several minutes, then it shuts down.  A local mechanic thought it might be the expansion valve.   Could it be something else...perhaps less complicated that ripping the dash apart?

The next place to look is the pressure switch, if it is going bad, it may trip off the clutch. I would make the expansion vavle the last thing to check, which will require tools to check. _____________________________ 96 XJ6 4.0, 05 XJ8 4.2 (in reply to opastu) Post #: 5
