My turn signals act like they have ground leching problems. on 1998 Buick Regal

turn on the left signal the white turning light doesn't come on but the signal flashes. turn on the right one the white turning light comes on but the light won't flash. checked easy stuff (flasher, replaced bulbs) cleaned grounds to core support No change. could this have to do with recall on parking lights? or some other ground wire?
