Help: No Headlights

[aztjc]

Tonight no headlights, 2002 LT, everything seems to work but the headlights.
No dims or brights.Have had the relay add on for years with no problems.
Pulled the relay and hear clicking when re inserted. Suspect maybe a bad ground somewhere. Any help or suggestions appreciated.
