My 89 GLI took 3 cans when I converted it to 134a. And you are correct, there is a minimum pressure to make the compressor engage. Something to consider, a test gauge costs about as much as a can of 134a; they're really quite cheap.

My A/C decided to hit the dust. Any idea how many cans of 134a would be needed to charge it back up? I added the one can that I had on the shelf and it did not work. I recall two cans did the trick a few summers ago in my Corrado. Am I correct in thinking that it needs so much refrigerant to have the compressor kick in? > > Anyhow, I just pulled the Gli out of hibernation since putting it away a few months ago in favor of the Corrado. > > Thanks, > > Jim > 91 Jetta Gli and others... > http://members.aol.com/jlpawlicki
