1993 GC autoheadlights not working

The dash lights come on when the sun goes down just like normal but the headlights do not. The headlights work if you manually turn the switch. Is this a bad Relay or what? If so which one? I think the relays for this on behind the glove box but again not sure. If there is a relay that I could swap to trouble shoot that would be great to know also.

Thanks
