    This is on a 94 car, so it came with R134a stock.

    I finally got around to fixing it after my compressor siezed up over a year ago. I put in a new compressor, accumulator, and a variable orfice tube. Had a vacuum drawn and it held, then proceded to fill it up with R134a.

    It wasn't blowing all that cold, cool but not near what it should be. Since the low side was sweating streams of water and because I thought I overfilled it, I removed some and it made it work slightly worse.

    Only thing I can think of is that the system doesn't like the variable orfice tube (sweating low side can be too big of orfice or overfilled).

    Any insights into this? Low side pressure is 38ish on a 90* day.

    yeah i would try putting in the proper orfice, or just giving it some more 134a.

      I don't even know where my sheet that came with the gauges I got for Melinda's T-bird went to, to see what the right pressure readings should be. If I run across it, I will let you know.
