Lights Always On

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

Turn "OFF" your Rain Sensing Windshield Wipers. :D

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.

Ditto on the rainsense ... when the auto wipers are in standby mode, the headlights are turned on.
