What could cause my Sierra to crank intermittently? It will start normally for days then suddenly not turn over. There is no clicking from the starter or a y attempted cranking at all. The lights and radio work. It will not start for days and then start cranking over again. The dome light stopped coming on when I open the door at the same time the issues started. The light will come on if you do it manually with the switch just not when the door is opened. The wires to the starter were a bit corroded so we're cleaned and I thought it might have worked but started acting up again the next day.
