Hi. I am new here. I have a 2006 Nissan Xterra. Have not had any problems lately but this morning out of the blue I do. I started my car to take my daughter to school and it was fine. Put the car in reverse and my dashboard flickered. Stepped on the gas and started backing out and the dashboard went completely dark and all needles fell to 0. Stepped on brake and it all came back on. Stepped on gas and they all went out again.Brake , again, back on. This continued for 1/4 mile. Turned out of my driveway onto the road and the guage went off again and this time my engine got sluggish. I pushed the gas but it wouldn't go any faster. All instruments were at 0 and the lights on the panel were out. SIDENOTE.... the radio and its display stayed on and it was also started raining this morning. Any advice would be welcome. I am a do it yourself kinda girl out of necessity so if anyone has any idea of what it is or what to check, i would greatly appreciate the help. Simply can not afford another mechanics bill as a one income single parent.
