95 S10 Headlight Problem

[WEEKEND WARRIOR]

The headlights will turn off then back on from time to time.

Seems to be worse the longer they are on.

 

A buzzing noise was coming from the relays in the glove box. (intermediately)

I replaced all three. Seems to be a little better but both promlems are still there.

 

I think it is the far relay to the right the run the headlights.

I think it is also the one buzzing.

 

What do these three relays run?

Any ideas on the problem?

Any wiring diagrams online?

 

Thanks
