Heads up Gang,
In my quest to figure out why my chassis a/c doesn't work i have discovered that even tho my chassis had it's compressor replaced (2018) that is not the end of the story. After several conversations with Eric Maclean he led me down the correct path to diagnose my a/c issue, tip of the hat to Eric. Thank you.
Eric told me to look at the top of my drier sight glass to see if I see bubbles or was it clear while the engine was running with the a/c on. "UH neither I see a bunch of white looking bb's." "oooohhh that's not good" or something along those lines. After much conflagration pulling this line off blowing air and brake kleen down this line and that, pulling apart expansion valves etc, I've discovered that I have the line from the condenser to the drier is completely packed solid with oil and bb's. To the point on the return from the condenser i had to drill out the line to make any head way, and it is still plugged on both ends and Im assuming the middle as well. So either the silica drier pellets took out the old compressor or when the old compressor grenaded it took out the silk/cotton fabric bag and released thousands of little tiny bits of gravel like material thru out my a/c system.
Questions that must be asked:
why didn't the previous owners tech replace the drier when the compressor was done? Yes I'm sure it is original one.
Why isn't there a screen into and out of the compressor to prevent these catastrophic events?
I'm going to try and patch this thing back together probably with the old compressor, but new drier(ya think!), expansion valve and a new hose. I figure I can burn allot of propane in my generator to run my coach a/c for the price of a new compressor if it all goes gunny sack.
Thank you and replace your drier!
