It starts slow n as I move the dial it gets higher, If I put it on full blast it will stop. The schematic diagram divide the entire vehicle electrical system into individual circuits, interacting electrical components are shown on one common schematic. When it does not blow cold air there is a slight noise coming from probably the compressor.
June 4, 2018 Followup from the Pelican Staff: Thanks for the feedback. I have heard that it is possible to use an R-12 compressor to do this, however it will require a total flush out of the compressor, as well as replacing all internal seals with R-134a compatible seals. .
