For the past few weeks, my dome lights will not go off. Dome Override does shut them off, but it must remain on. Also, power locks are not operating when you are driving. It will unlock, but if you hit lock, a ding, ding, ding alarm goes off. Today, while I was driving 30 miles an hour, steering and brakes just went out. Apparently, the engine had just shut down. Luckily, myself and my child were not injured, however, we did cross into the oncoming traffic lane and hit a curb before I could get the truck stopped. Anyone know of any specific electrical problems that could be causing these weird events?
