i have a 98 S 10 p/u 2.2 which has inop headlights. All other lights are working properly. all but the headlights come on automatically at night. There is no blue high beam indicator light on my dash either. Headlamp relay is good. High beams only on in daylight. will not switch from high to low. Help please.

 

Have you tried the manual method of turning them on from the switch?
