DRL and Low Beams wont turn on


Recommended Posts

Posted

2007 Chevy Silverado, New Body 1500 z71. Started the truck the other night. Headlights were on LOW when I first started the truck in the dark, When I put it in gear the headlights went out! Now the Day time running lights wont even turn on.

 

I've replaced the headlight relay, checked the bulbs and checked every single fuse in both panels just for the heck of it. Im out of ideas please help!

Check your grounds. Then check your wiring at the switch. Don't know the details on your truck, (locations, etc.) But it sounds like something's not making good contact.

Do the parking lights still work? Possible headlight switch? Like ride65 said: check the wiring at the switch for power.

Parking Lights still work,

 

HI Beams Still Work Too.

 

BTW.... When I twist the round light switch from AUTO to OFF to Marker Lights or Head Lights I can hear the relays clicking so they are getting power/ signal in every position.

That's strange. Maybe the multifunction switch is bad. Only works on high. If the headlights are messed up the DRL won't know when to come on. Does an 07 have separate bulbs for DRLs?

So did you check for power at the lowbeam/DRL sockets when you turn the lowbeam switch on?

    • Because that is IDIOTIC, much like this question. They've already been forced to do it by past administrations - why would you roll that back when it's a GOOD thing?  WHO IS ARGUING FOR LOWER MILEAGE???? 😂  NOBODY IS!!   I'm certainly not! What I want is RELIABLE vehicles again that are worth the price paid!    I don't get your logic here ...   In 2003 I paid $2,200 for our '86 Grand Marquis. It's STILL running and I've never been inside the engine, aside for the timing cover since it was leaking, so I threw a new timing set in since that makes sense. Transmission is ORIGINAL. Electric pump in the gas tank is ORIGINAL. Rear end is ORIGINAL. I'd have to hit my head REAL hard to want to pay $60k or more for a car that still can't come close to the comfort, seating and storage space, or reliability of this one. Nothing is even in the ball park! Hundreds of thousands of brands and models have been built and sent to the crusher while this one keeps on going!   https://postimg.cc/Z9XRrCSg   I've got a whole fleet of cars, motorcycles, and a truck close to this age for summer and winter. No one could pay me enough to buy anything built this century. I have zero use for any it.
    • Since I'm the one who has to fix them when they break, I'll take vehicles over 30 years old all day, EVERY day, over ANY modern crap. Have you attempted any repairs on anything built after 2006? It's a friggin nightmare, and gets worse the newer the model year.    If I had the will or desire, I can make any car of any age outside of a Model T (I don't have THAT much will ...) just as powerful, comfortable, and have all the tech the new stuff does, and get pretty close in mileage, too. I prefer SIMPLICITY. The less the vehicle has, the less to fix WHEN it breaks, not IF.   I'm glad you snot-nosed punks don't like them. More for us, plus that keeps the prices from climbing more than they already have.👍
    • Bringing this thread back on topic. I just noticed the incredible lack of bright chrome across the entire new lineup. Even the Denali has tinted the brightwork in the grille and has none elsewhere. None of them have chrome bumpers. As far as I can tell there aren't even chrome mirror caps. I'm curious if this also happens out back? Are there no chrome rear bumpers either? This is quite the departure for GMC.
