headlight problem
1993 buick regal
all three are out daytime running lights, lo and hi beam so there is no lights
but all brake lights and parking lights signal hazard all work i replaced headlight switch but sit nothing

I gotta ask, but have you checked the bulbs? If they are fine and the fuse is fine, I would suggest a faulty relay.

yep checked the bulbs have check all the fuses but i am unable to locate the headlight relay i have wiring diagram but does not show location if it
