My daytime running lights have quit coming on instead the headlights run all the time now like its dark. Any suggestions?

 

is it all your lights? or just the headlights?...........check the sensor and make sure it is not covered up with anything on the dash.

 

what year truck? my ex girl had a 99 new body silverado that did the same thing... never did figure it out, so im interested lol

 

Yeah that sensor that looks like a nipple on the dash near the windshield is the sensor.

 

DTRLs burned out? Blown fuse?

 

My '03 had the same problem when i bought it. Finally after looking at other trucks, realized the sensor had fell down inside. The salesman that sold me the truck actually payed out of his own pockets to fix/retrieve the sensor, and it has worked great since.

 

Its a 2000 sierra and the daytime bubs are good and all the lights come on like its dark and I have cleaned the sensor. Am afraid that I am going to have to take the dash apart and replace the sensor.
