bought used from dealer 3 months ago. about 2 months ago noticed odometer light flickering slightly. Now fuel gauge jumps up and down after driving a while, radio turns on and off and now the headlights are flickering slightly – like in time with the odometer lights. I don’t notice the headlight flickering while driving as it is slight – almost jittery. PLEASE help – we are traveling 2000+ miles from home and will be on the road for 2 more weeks!
