There are multiple fittings from the back of compressor to the front of the coach. Our leaks came from high side fitting on back of compressor. You could easily see the dust caked up on the hose where small amounts of oil/Freon was leaking out. We also found hi-side port fitting leaking. Since we had compressor off to replace o-ring, it was replaced with a reman from freight liner house. The hi side fitting was replaced. System vacuum tested and recharged. All good. She’s blowing ice cubes again. Cost was under 600. As stated previous, the fix-a-flat Freon is an a/c systems worst nightmare.
