I have a 1997 GMC Jimmy S-15. The problem that I am having is that my
headlights are cutting on and off randomly while I am driving. The
daytime lights are fine, it only happens while the headlights are
engaged.
While the lights are cutting off there is a clicking sound and the
source seems to be one of the relays in the glove box. The problem
seems to be reduced while my High-Beams are engaged.
Does anyone know if replacing the relay will help? Or does anyone know
which relay is the headlight relay? There are 3 inside the glovebox.

Thanks,
Dave
