mike33 Posted July 31, 2009 Report Share Posted July 31, 2009 Hello Gentlemen, I have a 2002 Deville DHS and the lights are always on even in bright sunshine. They will not go off unless you slide the 'twilight' to off. Then it says headlamps suggested. There are no objects covering the sensor on the dash. Any suggestions on where to start?? Thanks in Advance, Mike Link to comment Share on other sites More sharing options...

JohnnyG Posted July 31, 2009 Report Share Posted July 31, 2009 Or reconnect or replace your sun sensor mounted on top of the dash. It's the one that tells your headlights that it is daylight outside. Never underestimate the amount of a persons greed. Link to comment Share on other sites More sharing options...
