High beam headlights stuck on replaced switch same problem


It can be issue with headlight switch,but as its already been replaced.Try disconnecting high beam headlight wiring from headlight assembly and reconnect direct external wire from headlight switch to headlight assembly,then by switch see if headlight is getting off and turning on or not.

Other possibilities are; the bulbs themselves, burnt or corroded bulb sockets, or a bad headlight selector switch.

Why are my headlights not working on my denali


Can simply be the low beam elements are bad in bulbs, or the dimmer switch itself or could simply be the fuses to the low beam elements in the fuse panel. Often the high beam and low beam are on seperate fuse links. Ck the fuse boxes both inside and under the hood. hope it helps, TH,

Headlights went out. Replaced bulbs and switch and still lights don't work. Fog lights and high beams work? What else can work?


If high beams work and low beams do not, then it is probably the high/low relay. It is part number 15016745 and has four prongs. To test if your relay has gone bad locate the relay in your fuse box. There will be two of these relays located next to each other. One controls the low beam headlights and the other the cooling fan. Swap the relays and check your low beam headlights. If the low beams work you have a bad relay.

Driver side head light does not work...the high beam does


Change the bulb. High and low beams are separate bulbs located in the headlight housing. Im not sure on the 07 but the earlier design Yukon (02)you have to pull out a pin located under the hood on the top of the light housing in order to remove it.

I have a 2006 GMC Denali. THe low beam on the driver's side is out. Hi Beam works fine. I suspect a bulb. How does one go about replacing a low beam bulb on the Denali? Thanks for your help! M...


Should be two metal rods that hold the headlight assembly in place unsnap the rods from the holders and lift the rods out and you should be able to pull the whole assembly out giving you access to the bulbs.

Low beams stopped working high beams work fine


Either both bulbs are bad(I've seen it before) or your
dimmer/headlight switch is bad. If you can without pulling the bulb, pull plug from the light. If it's a 4 lamp system pull the low beam. Do this on the left side as the right feeds from the left. With a 12v test light, check for power. (with lo beam on) if you have
power, change the lamp, if you don't it's most likly
the dimmer switch at the steering collum.
Hope this helps Good luck

Change head light


You should be able to reach under the hood into the headlight assembly and grab the bulbs and twist them off if not then you have to take off your entire headlight assembly then take the bulbs out.
