The automatic headlights on my 1999 Silverado dont turn on when the truck is started. I have to turn the switch on to have headlights. Any thoughts?

 

Is your sensor on your dash bein covered up? Or did it come unplugged somehow?

 

My 97 did the same thing. I saw it as divine intervention as im not a fan of day time running lights. My alternator had went out an hour from home, had to drive with the parking brake on one click to turn off the day time running lights to get home.

 

The sensor isn't covered. Where is it plugged in at? I have a feeling its going to be under the dash.

 

You sir are correct. Right under the dash is where it's at

 

Thanks for the tips. Ill check it out.
