Does anyone know the procedure or have a manual that shows how to remove and replace the turn signal switch (multi function switch) on a 2000 F-150. I am having intermittent failure of turn signals and I believe I need to replace the switch. When the signals quit on me, if I jiggle the lever or move the tilt wheel up and down, most of the time they will start working again for awhile. If anyone can start me in the right direction I'd appreciate it. Thanks.
