So I've searched to see see how to make them work, but I see more threads on disabling them. My Headlights come on all the time when I start up. I've pressed the DOME OVERIDE button 4 times to make the headlights go out which is cool. I've checked the fuse and its fine. I've replaced the bulbs and sockets. One socket was burned and the other missing. I also replaced the relay just in case. But still no worky. The headlights come on still day or night. Any suggestions.

so let me get this straight your headlights are on all the time you want them off during the day and the drl's on?

 

Thats right. Headlight Off During the day and the DRL's on.

 

Something has gone wrong with your light sensor on the dash.[/align]

 

very possible the sensor has fell in the dash i have seen several like that they arnt held on very well

 

what is the problem? that's how they are supposed to work. you turn the key, DRLs come up. dusk falls, headlights come up.

 

The Problem is... the DRL's don't come up when I turn the key.

I'll check the sensor.
