I believe MOST current vehicles with A/C installed will run the compressor even in winter at times to reduce humidity in the vehicle in DEFROST mode. Therefore Emery's recommendation probably applies primarily to older vehicles and our buggies are definitely in that category!

Thanks Emery. I will try releasing a bit of refrigerant tomorrow. And I had never thought of running the ac in the winter. I'll try that this
winter and see how it looks next spring. With a leak this slow, if it's just a matter of topping it up a bit each season, I can live with that for
now. But if running the compressor occasionally will prevent that, happy to do it. My coach just sits from Oct/Nov to Apr/May, depending on when the
snow comes and melts. Can't do much with her in the winter up here. Sometimes I shovel a path to the door and go in and sigh! :cry:
