My roof-mounted dvd player has never worked but still makes noises when car is crunk up or switched off, my battery all of a sudden went dead (car would not crank), headlights have shorts in them. . . After replacing $100 bulbs, I found out if I turn the lights off and back on, the bulb will come back on, check park assist light and alarms come on every time the vehicle is put in reverse, and my suspension will not let the vehicle up when the weather is cold.
