Daytime running lights not working

[hcetri]

I am having a problem with my daytime running lights. They are not working but my headlights stay on all the time when my truck is running. Does this have anything to do with the sensor on the dash?

Yes. Its the daylight sensor. If you have it covered, the headlights will stay on. It could possibly need replacing. Shine a flashlight directly on it for a few minutes and see if the headlights go off. If not, I'd say it was bad.

Thanks I'll try the flashlight .A new sensor is about $12.00 at the dealer.
