My g/f's 98 for some reason only has reverse lights SOMETIMES. We think that it has to do w/ some kind of switch that is toggled when you shift into reverse. If we jiggle the shift handle around a little they will come on and off so we are thinking either the linkage needs to be tightened or this switch that is triggered is off somehow...her bro knows how to fix it if it is the switch but he said he had trouble finding it...does anyone know where the switch can be found? Thanks for any help.
