Diod you charge the a c if its low by that i mean if it needs a charge the compressor has a cut out switch inline with the power wire going to the a c compressor clutch it can also be referred to as a fuse depending on who you arer speaking with it is there to protect the compressor from burning out.
Any thing i m missing or do i need to start looking for a broken wire somewhere.
