[Vwdiesel] A/C Compressor?

[lbaird119 at aol.com]

Well, warm weather is here (then gone, then  here...)  So the wife wants the A/C to work.  It halfway pooped out as we were coming home, through NV.  Turn it off a bit, then on and it'd blow cool for a while until I'd turn it off, wait then back on.
  Eventually I paid the ransom and put a can of 134a in it.  It didn't really help.  Took it to a friend that I borrow stuff from and has done me good on diagnosing stuff that flusters me.  Pressures were too high (overcharged) and not really doing much.  He concluded the expansion valve was the culprit.
  Yesterday I pumped out 4 an da dab cans of freon (one blew the relief out of the bottom so there went one can of salvage!)  I changed the valve and o-rings except for one wrong sized one they sent, recharged it and poop!  Low side drops about 10psi or so, when it kicks on.  Compressor stays running, low doesn't drop, high doesn't climb.

  So, what's the consensus, bad compressor?  Never had one before.  Anybody have a good one sitting on a shelf, to fit a B4 Passat?  :-)
