My Vacuum pump has stopped working so I have no auto-lock hubs and my A/C only blows from my defroster. I am not sure that the pump has gone bad because I have tested for voltage at the plug into the pump and there is none. I was wondering if it could be a relay or fuse gone bad (if so which one) or is there maybe a presure switch/valve that might not be telling the pump to turn on???
