Hello all,
I have a 2000 F-150 with what seems like a loose ground somewhere. The cluster illumination including the odometer and radio only light up occassionally and intermittently. The problem is so widespread yet minor that I am led to believe its just a loose ground somewhere. Does anybody know where the grounding point for this circuit is or have a link to some wiring diagrams? Thanks in advance!

 

Could be the dimmer/main headlamp switch.. If you loosing all illumination in all the window switches, ash tray ect. than look at the H/L switch..The ground for the illumination is in the right kick panel...
