headlight and speedo prob.
so i have a 1998 ranger 4wd 4.0 v6 5 speed.
when im driving at night my headlights shutoff and i have to wiggle my turn signal lever/high beam lever to get them to come back on or i have to hold it. also some times my speedo works and some times it doesn't. or sometimes it bounces. any suggestions why this happen would be much appreciated.
