When i try to start the vehicle , turn key to on, all dash lights come on as they should, then as I go to start the vehicle all lights on dash go out and no starter action... Then if I go out and open and close hood a couple of times with a bang then the lights will come on again and when I try to start it starts????? This seems to act up more so when we have damper weather ...... Also it doesn't do it all the time??? Any suggestions on what to look for.... Thanks Dw
