My turn signals and my headlights have stopped working. If I hold the turn signal lever in the 'high beam' position, I have head lights. While driving home last night (DARK) two messages came up: trunk open, air bags. The parking lights and rear lights stayed on after motor was shut off. I pulled fuse #20 (I think) in order to get them off as I didn't have the correct tool nor the strength to take the battery cables off. Please advise.
