ANY ONE KNOW WHERE THE HIGH BEAM SWITCH IS LOCATED ON A 99 D? IS IT ON THE COLUMM UNDER THE DASH LIKE GM. MINE I THINK IS TOAST WHEN I PUT PUT THEM ON MY LIGHTS GO OUT AND I HAVE TO KEEP CLICKING THE SWITCH TO TRY AND GET THE LOW BEAMS BACK NOT FUN ON THE DARK BACK ROADS

 

I believe its located in the Column.... But you might want to check the Relays / Fuses first. They should be independant from each other.
