At night my headlamps go off for short periods of time while driving. After 30 seconds or so they go right back on again. Who can help????

This is on a 2000 C5 Coupe

 

I'd start with grounds and the battery connections. give them a clean up and tighten the connections

 

Yes, I started there by looking at the connections, but the problem continues. No loose wires either....

 

Check your codes.

Thanks!

 

Your welcome, hope you get it fixed. Intermittent electrical problems are tough to fix. Seems like a short in the "circuit breaker" circuit or perhaps a bad circuit breaker.
