1991 mazda protege dx
 

i have a 1991 mazda protege dx and the high beams will not work, what can it be?

Have you tested the bulbs?
Do you have power & earth to the bulbs?
Have you checked fuses?

i actually found out what it was, the bulbs were bad! i didn't know bad bulbs could still light up , that's what threw me off after i spent money for nothing on the switch !
