That’s a good video. I have the same Sanden compressor kit in my 1105. I believe I lost the charge over winter and haven’t had time to troubleshoot. I believe the culprit is the high side Schrader valve on the compressor is leaking. Like yours, when the AC is working, it gets cold and makes a lot of condensation in these very humid mountains. How many lbs of 134a are you putting in after evacuating the system? Or do you use another method to meter in the charge? Thanks for the video!
