my 2007 silverado classic Z71 has a few lighting issues. first off my day time running lights dont work at all. the bulbs were burnt out but i changed them and nothing i checked the relays and they seem to be fine. however i did not find a relay specifically labeled day time running lights or DTRL.
second i have the audio buttons on my steering wheel are going out one by one and the buttons under my clock are doing the same thing only one so far but i dont wanna be with out anymore my steering is already looking bad
any advice would be great thanks

 

I'm not sure how to approach your button issues, but for your DRL issue, check your fuses. (If you haven't already; if you have I apologize).

 

The buttons may not have individual lights, sometimes a single light will light up a few buttons, at any rate replace them, also check fuses, i'm pretty sure your daytime running lights aren't on a relay, but than again I could be wrong. Good luck though

 

Depending on your current mileage you may still be under the 3 year 36,000 mile bumper to bumper warranty. You should be able to speak with your local dealership and be able get this issue remedied, under normal circumstances. I hope that helps you.

make sure the vehicle is running in park and the parking brake is off and verify if the DRL's are still off....
