I have a 2001 Silverado Z71 ext. cab. The headlights and daytime driving lights stopped working. High beams work, and all other lights work. I checked all the fuses and replaced the relay. Any suggestions?

 

Check your bulbs?

 

I did that also.

 

Check the headlight switch. I had this happen on my ranger I turned the switch and had parking lights and high beams when I pushed and pulled the multipurpose switch but no head lights

 

I replaced the headlight switch, and I have DRL, High beams, everything but regular HL. They came on once when I started the truck, stayed on until I shut it off. Then started it again and they didn't come on. Maybe a bad connection or ground.
Thanks for the replies.

 

That's possible that you have a bad ground. Your welcome for the replies though I don't think I'm helping much lol it's hard to diagnose a car when it's not in front of you I'm just throwing ideas out there with out trying to make you spend money on it
