Daytime running lights off

Sampson, sounds like a bunt out bulb, which will need changed.
If you feel comfortable doing it yourself. Basically three screws, and you have to pull one plastic fastener from the fascia (bumper) and pull the bumper back a bit, and pull the assembly out. I believe it is in the manual, not bad to do. I will post a link to tell or show you how to do it. Press the helpful button

Headlight Bulbs

The problem was a bad left front blinker socket that was grounding out

headlight switch replace.and turn signal there all together in the same switch

if you have the owners manual it should give proper amp and location of fuses otherwise check both sides of each fuse with a test light for power when you find the one with power only on one side remove and replace that fuse the lighter fuse should have power with key off some fuses need key on to light up at all and some will need items such as headlights turned on to light

Is neither the high beam nor low beam working? Neither the left side nor the right side for each? Knowing this could help isolate the problem. It could be anything from a simple case of blown headlamp bulbs to a burned-up headlamp switch to a defective Daytime Running Lamp Module. I will say, however that I have seen quite a few problems with the headlamp bulb sockets on several of the GMs.

there is a relay under the hood in the fuse/relay panel called drl, or daytime running lamps, that relay is most likely bad, a good way to tell is switch it with the high beam relay, if they come on you know thats it, if they dont, its the relay for the lowbeams, again switch it with the high beam relay and see.. either way i can tell you for sure one of those two are bad... but most of the time it is the daytime running lamps, or sometimes called driving lights relay. hope this helps you

First, be sure that the headlights are actually coming on. These cars have daytime running lights that use the headlight bulbs at a lower voltage. If the car is only using the daytime running lights, the tail lights will not be on with the headlights. The multifunction lever always turns on the high beams when you pull on it (it's called 'flash to pass'). Make sure the headlight switch is working, and also check the headlight circuit breaker.

hello, the left and right headlight fuses are powered by the same circuit. the circuit is bus bar inside the fuse block. if you are 100 percent sure the fuse is dead, then the only possiblitie is a bad fuse block

Daytime running light module!!!! $400.00 from the dealer..lol

Go through all your fuses, Dim lights run on a separate fuse.
